Jamieson, Fausset & Brown

On Joshua 8:3

So Joshua . . . chose out thirty thousand mighty men of valour - Joshua despatched thirty thousand men under cover of night, to station themselves at the place appointed for the ambuscade. Out of this number a detachment of five thousand was sent forward to conceal themselves in the immediate precincts of the town, in order to seize the first opportunity of throwing themselves into it [Jos 8:12].

John Gill

On Joshua 8:3

So Joshua arose, and all the people of war, to go up against Ai,.... As the Lord had commanded him:

and Joshua chose out thirty thousand mighty men of valour; out of all the men of war; these were a select company, picked men, not the whole army, as some have thought, for he was ordered to take all the people of war, as he did:

and sent them away by night; from the main army, that they might pass the city and get behind it undiscovered, for they were sent for an ambush; and of these some were to take the city, and be left in it to burn it, and some to smite the men of Ai, as Abarbinel notes.

Keil & Delitzsch

On Joshua 8:1-29

Conquest and Burning of Ai. - Jos 8:1, Jos 8:2. After the ban which rested upon the people had been wiped away, the Lord encouraged Joshua to make war upon Ai, promising him that the city should be taken, and giving him instructions what to do to ensure the success of his undertaking. With evident allusion to Joshua's despair after the failure of the first attack, the Lord commences with these words, "Fear not, neither be thou dismayed" (as in Deu 1:21; Deu 31:8), and then commands him to go against Ai with all the people of war. By "all the people of war" we are hardly to understand all the men out of the whole nation who were capable of bearing arms; but as only a third of these were contributed by the two tribes and a half to cross over into Canaan and take part in the war, the other tribes also are not likely to have levied more than a third, say about 160,000, which would form altogether an army of about 200,000 men. But even such an army as this seems out of all proportion to the size of Ai, with its 12,000 inhabitants (Jos 8:25). On the other hand, however, we must bear in mind that the expression "all the people of war" simply denotes the whole army, in contrast with the advice of the spies that only a portion of the army should be sent (Jos 7:3), so that we are not warranted in pressing the word "all" to absolutely;

(Note: "As we have just before seen how their hearts melted, God consulted their weakness, by putting no heavier burden upon them than they were able to bear, until they had recovered from their alarm, and hearkened readily to His commands." - Calvin.)

and also that this command of God was not given with reference to the conquest of Ai alone, but applied at the same time to the conquest of the whole land, which Joshua was not to attempt by sending out detachments only, but was to carry out with the whole of the force at his command. עלה, to go up, is applied to the advance of an army against a hostile town, independently of the question whether the town was situated upon an eminence or not, as every town that had to be taken was looked upon as a height to be scaled, though as a fact in this instance the army had really to ascend from Jericho to Ai, which was situated up in the mountains (On Jos 8:1, see Jos 6:2.) "His land" is the country round, which belonged to the town and was under its king.

Jos 8:2

Joshua was to do the same to Ai and her king as he had already done to Jericho and her king, except that in this case the conquerors were to be allowed to appropriate the booty and the cattle to themselves. In order to conquer the town, he was to lay an ambush behind it.

(Note: The much agitated question, whether it could be worthy of God to employ stratagem in war, to which different replies have been given, has been answered quite correctly by Calvin. "Surely," he says, "wars are not carried on by striking alone; but they are considered the best generals who succeed through art and counsel more than by force ... . Therefore, if war is lawful at all, it is beyond all controversy that the way is perfectly clear for the use of the customary arts of warfare, provided there is no breach of faith in the violation of treaty or truce, or in any other way.")

ארב, a collective noun, signifying the persons concealed in ambush; מארב (Jos 8:9), the place of ambush. "Behind it," i.e., on the west of the town.

Jos 8:3-9

Accordingly Joshua set out with all the people of war against Ai, and selected 30,000 brave men, and sent them out in the night, with instructions to station themselves as an ambuscade behind the town, and at no great distance from it. As the distance from Gilgal to Ai was about fifteen miles, and the road runs pretty straight in a north-westerly direction from Jericho through the Wady Faran, the detachment sent forward might easily accomplish the distance in a night, so as to arrive on the western side of Ai before the break of day. They were then to hold themselves in readiness to fight. He (Joshua) himself would approach the town with the people of war that remained with him; and if the inhabitants of Ai should come out against him as they did before, they would flee before them till they had drawn them quite away from their town (Jos 8:5). This was to be expected; "for they will say, They flee before us, as at the first: and we will flee before them" (Jos 8:6). When this was done, the warriors were to come forth from their ambush, fall upon the town, and set it on fire (Jos 8:7, Jos 8:8). Having been sent away with these instructions, the 30,000 men went into ambush, and posted themselves "between Bethel and Ai, on the west side of Ai" (Jos 8:9), i.e., according to Strauss, in the Wady es Suweinit, to the north-west of Ai, where it forms almost a perpendicular wall, near to which the ruins of Chai are to be found, though "not near enough to the rocky wady for it to be possible to look down its almost perpendicular wall" (Ritter, Erdk. xvi. p. 528). Joshua remained for the night in the midst of the people, i.e., in the camp of that portion of the army that had gone with him towards Ai; not in Gilgal, as Knobel supposes.

Jos 8:10

The next morning he mustered the people as early as possible, and then went, with the elders of Israel, "before the people of Ai." The elders of Israel are not "military tribunes, who were called elders because of their superiority in military affairs," as Masius supposes, but, as in every other case, the heads of the people, who accompanied Joshua as counsellors.

Jos 8:11-13

The whole of the people of war also advanced with him to the front of the town, and encamped on the north of Ai, so that the valley was between it (בינו, as in Jos 3:4) and Ai. This was probably a side valley branching off towards the south from the eastern continuation of the Wady es Suweinit. - In Jos 8:12, Jos 8:13, the account of the preparations for the attack is founded off by a repetition of the notice as to the forces engaged, and in some respects a more exact description of their disposition. Joshua, it is stated in Jos 8:12, took about 5000 men and placed them in ambush between Bethel and Ai, on the west of the town. As the place where this ambuscade was posted is described in precisely the same terms as that which was occupied, according to Jos 8:9, by the 30,000 men who were sent out to form an ambuscade in the night before the advance of the main army against Ai (for the substitution of "the city" for Ai cannot possibly indicate a difference in the locality), the view held by the majority of commentators, that Jos 8:12 refers to a second ambuscade, which Joshua sent out in addition to the 30,000, and posted by the side of them, is even more than questionable, and is by no means raised into a probability by the expression את־עקבו (Eng. "their liers in wait") in Jos 8:13. The description of the place, "on the west of the city," leaves no doubt whatever that "their liers in wait" are simply the ambuscade (ארב) mentioned in Jos 8:12, which was sent out from the whole army, i.e., the ambuscade that was posted on the west of the town. עקב signifies literally the lier in wait (Psa 49:5), from עקב, insidiari, and is synonymous with ארב. The meaning which Gesenius and others attach to the word, viz., the rear or hinder part of the army, cannot be sustained from Gen 49:19. If we add to this the fact that Jos 8:13 is obviously nothing more than a repetition of the description already given in Jos 8:11 of the place where the main army was posted, and therefore bears the character of a closing remark introduced to wind up the previous account, we cannot regard Jos 8:12 as anything more than a repetition of the statements in Jos 8:3, Jos 8:9, and can only explain the discrepancy with regard to the number of men who were placed in ambush, by supposing that, through a copyist's error, the number which was expressed at first in simple letters has in one instance been given wrongly. The mistake, however, is not to be found in the 5000 (Jos 8:12), but in the 30,000 in Jos 8:3, where ה has been confounded with ל. For a detachment of 5000 men would be quite sufficient for an ambuscade that had only to enter the town after the soldiers had left it in pursuit of the Israelites, and to set it on fire, whereas it hardly seems possible that 30,000 men should have been posted in ambush so near to the town.

(Note: We need have no hesitation in coming to the conclusion that there is a mistake in the number given in Jos 8:3, as the occurrence of such mistakes in the historical books is fully established by a comparison of the numbers given in the books of Samuel and Kings with those in the books of Chronicles, and is admitted by every commentator. In my earlier commentary on Joshua, I attempted to solve the difficulty by the twofold assumption: first, that Jos 8:12 contains a supplementary statement, in which the number of the men posted in ambush is given for the firs time; and secondly, that the historian forgot to notice that out of the 30,000 men whom Joshua chose to make war upon Ai, 5000 were set apart to lie in ambush. But, on further examination of the text, I have come to the conclusion that the second assumption is irreconcilable with the distinct words of Jos 8:3, and feel obliged to give it up. On the other hand, I still adhere to the conviction that there is not sufficient ground either for the assumption that Jos 8:12, Jos 8:13, contain an old marginal gloss that has crept into the text, or for the hypothesis of Ewald and Knobel, that these verses were introduced by the last editor of the book out of some other document. The last hypothesis amounts to a charge of thoughtlessness against the latest editor, which is hardly reconcilable with the endeavour, for which he is praised in other places, to reconcile the discrepancies in the different documents.)

- In Jos 8:13, העם (the people) is to be taken as the subject of the sentence: "The people had set all the host, that was on the north of the city, and its ambuscade on the west of the city." In the night, namely the night before the army arrived at the north of the town, Joshua went through the midst of the valley, which separated the Israelites from the town, so that in the morning he stood with all the army close before the town.

Jos 8:14-23

When the king of Ai saw the Israelites, he hurried out in the morning against them to battle at the (previously) appointed place (למּועד, in locum condictum, as in Sa1 20:35) before the steppe (Arabah, not the valley of the Jordan, but the steppe or desert of Bethaven; see at Jos 7:2), as he knew nothing of the ambuscade behind the town.

Jos 8:15

But the Israelites let them beat them, and fled along the desert (of Bethaven).

Jos 8:16-17

And all the people in the town were called together to pursue the Israelites, and were drawn away from the town, so that not a man, i.e., not a single soldier who could take part in the pursuit, remained either in Ai or the neighbouring town of Bethel, and the town stood open behind them. It is evident from Jos 8:17 that the inhabitants of Bethel, which was about three hours' journey from Ai, took part in the battle, probably in consequence of a treaty which the king of Ai had made with them in the expectation of a renewed and still stronger attack on the part of the Israelites. Nothing further is known upon this point; nor can anything be inferred from the fact that the king of Bethel is included in the list of the kings slain by Joshua (Jos 12:16). Consequently, we cannot decide whether the Bethelites came to the help of the Aites for the first time on the day of the battle itself, or, what is more probable, had already sent men to Ai, to help to repulse the expected attack of the Israelites upon that town.

Jos 8:18-19

At the command of God Joshua now stretched out the javelin in his hand towards the town. At this sign the ambuscade rose hastily from its concealment, rushed into the town, and set it on fire. בּכּידון נטה signifies to stretch out the hand with the spear. The object יד, which is missing (cf. Jos 8:19, Jos 8:26), may easily be supplied from the apposition בּידך אשׁר. The raising of the javelin would probably be visible at a considerable distance, even if it was not provided with a small flag, as both earlier and later commentators assume, since Joshua would hardly be in the mist of the flying Israelites, but would take his station as commander upon some eminence on one side. And the men in ambush would have scouts posted to watch for the signal, which had certainly been arranged beforehand, and convey the information to the others.

Jos 8:20-22

The men of Ai then turned round behind them, being evidently led to do so by the Israelites, who may have continued looking round to the town of Ai when the signal had been given by Joshua, to see whether the men in ambush had taken it and set it on fire, and as soon as they saw that this had been done began to offer still further resistance to their pursuers, and to defend themselves vigorously against them. On looking back to their town the Aites saw the smoke of the town ascending towards heaven: "and there were not hands in them to flee hither and thither," i.e., they were utterly unable to flee. "Hand," as the organs of enterprise and labour, in the sense of "strength," not "room," for which we should expect to find להם instead of בּהם. There is an analogous passage in Psa 76:6, "None of the men of might have found their hands." For the people that fled to the wilderness (the Israelitish army) turned against the pursuers (the warriors of Ai), or, as is added by way of explanation in Jos 8:21, when Joshua and all Israel saw the town in the hands of the ambuscade, and the smoke ascending, they turned round and smote the people of Ai; and (Jos 8:22) these (i.e., the Israelites who had formed the ambuscade) came out of the town to meet them. "These" (Eng. the other), as contrasted with "the people that fled" in Jos 8:20, refers back to "the ambush" in Jos 8:19. In this way the Aites were in the midst of the people of Israel, who came from this side and that side, and smote them to the last man. "So that they let none of them remain:" as in Num 21:35 and Deu 3:3, except that in this case it is strengthened still further by וּפליט, "or escape."

Jos 8:23

The king of Ai was taken alive and brought to Joshua.

Jos 8:24-26

When all the men of Ai, who had come out to pursue the Israelites, had been slain upon the field (namely) in the desert, all Israel returned to Ai and smote it (the town, i.e., the inhabitants), so that on that day there fell of men and women, 12,000, all the people of Ai: for Joshua did not draw back his hand, which had been stretched out with the javelin, till all the inhabitants of Ai were smitten with the ban, i.e., put to death; according to the common custom of war, that the general did not lower the war-signal till the conflict was to cease (see Suidas in Σημεῖα, and Lipsius de militia, Rom. iv. dial. 12).

Jos 8:27

Only the cattle and the rest of the booty the conquerors retained for themselves, according to the word of the Lord (Jos 8:2).

Jos 8:28

Joshua had the town burnt down and made into a heap of rubbish for ever.

Jos 8:29

He had the king of Ai hanged upon a tree, i.e., put to death, and then suspended upon a stake (see Num 25:4) until the evening; but at sunset he had him taken down (in accordance with Deu 21:22-23), and thrown at the entrance of the town-gate, and a heap of stones piled upon him (as in the case of Achan, Jos 7:26).

Matthew Henry

On Joshua 8:3-22

We have here an account of the taking of Ai by stratagem. The stratagem here used, we are sure, was lawful and good; God himself appointed it, and we have no reason to think but that the like is lawful and good in other wars. Here was no league broken, no treaty of peace, that the advantage was gained; no, these are sacred things, and not to be jested with, nor used to serve a turn; truth, when once it is plighted, becomes a debt even to the enemy. But in this stratagem here was no untruth told; nothing was concealed but their own counsels, which no enemy ever pretended a right to be entrusted with; nothing was dissembled, nothing counterfeited but a retreat, which was no natural or necessary indication at all of their inability to maintain their onset, or of any design not to renew it. The enemy ought to have been upon their guard, and to have kept within the defence of their own walls. Common prudence, had they been governed by it, would have directed them not to venture on the pursuit of an army which they saw was so far superior to them in numbers, and leave their city unguarded; but (si populus vult decipi, decipiatur - if the people will be deceived, let them) if the Canaanites will be so easily imposed upon, and in pursuit of God's Israel will break through all the laws of policy and good management, the Israelites are not at all to be blamed for taking advantage of their fury and thoughtlessness; nor is it any way inconsistent with the character God is pleased to give of them, that they are children that will not lie. Now in the account here given of this matter,

I. There is some difficulty in adjusting the numbers that were employed to effect it. Mention is made (Jos 8:3) of 30,000 that were chosen and sent away by night, to whom the charge was given to surprise the city as soon as ever they perceived it was evacuated, Jos 8:4, Jos 8:7, Jos 8:8. And yet afterwards (Jos 8:12) it is said, Joshua took 5000 men and set them to lie in ambush behind the city, and that ambush entered the city, and set it on fire, Jos 8:19. Now, 1. Some think there were two parties sent out to lie in ambush, 30,000 first, and afterwards 5000 to guard the roads, and to intercept those that were first sent out; and that Joshua made his open attack upon the city with all the thousands of Israel. So the learned bishop Patrick, insisting upon God's command (Jos 8:1) to take all the people of war with him. But, 2. Others think that all the people were taken only to encamp before the city, and that out of them Joshua chose out 30,000 men to be employed in the action, out of which he sent out 5000 to lie in ambush, which were as many as could be supposed to march incognito - without being discovered (more would have been seen, and thus the design would have been broken) and that then with the other 25,000 he made the open attack, as Masius thinks, or with the 30,000, which, as Calvin thinks, he kept entire for that purpose, having, besides them, sent out 5000 for an ambuscade. And those 5000 (they think) must be meant by those (Jos 8:3) whom he sent away by night, with orders to lie in wait behind the city, though the particular number is not specified till Jos 8:12. If we admit such a seeming disturbance in the order of the narrative (of which, perhaps, similar instances might be cited from the other scripture histories), it seems most probable that there was but one ambushment, which consisted only of 5000, enough for such a purpose.

II. Yet the principal parts of the story are plain enough, that a detachment being secretly marched behind the city, on the other side to that on which the main body of the army lay (the situation of the country, it is probable, favouring their concealment), Joshua, and the forces with him, faced the city; the garrison made a vigorous sally out upon them, whereupon they withdrew, gave ground, and retreated in some seeming disorder towards the wilderness, which being perceived by the men of Ai, they drew out all the force they had to pursue them. This gave a fair opportunity for those that lay in ambush to make themselves masters of the city, whereof when they had given notice by a smoke to Joshua, he, with all his force, returned upon the pursuers, who now, when it was too late, were aware of the snare they were drawn into, and, their retreat being intercepted, they were every man of them cut off. The like artifice we find used, Jdg 20:30, etc. Now in this story we may observe,

1. What a brave commander Joshua was. See, (1.) His conduct and prudence. God gave him the hint (v. 2) that he should lay an ambush behind the city, but left him to himself to order the particulars, which he did admirably well. Doubtless wisdom strengthens the wise more than ten mighty men, Ecc 7:19. (2.) His care and industry (Jos 8:10): He rose up early in the morning, that he might lose no time, and to show how intent his mind was upon his business. Those that would maintain their spiritual conflicts must not love their ease. (3.) His courage and resolution; though an army of Israelites had been repulsed before Ai, yet he resolves to lead them on in person the second time, Jos 8:5. Being himself also an elder, he took the elders of Israel with him to make this attack upon the city (Jos 8:10), as if he were going rather to sit in judgment upon them as criminals than to fight them as enemies. (4.) His caution and consideration (Jos 8:13): He went that night into the midst of the valley, to make the necessary dispositions for an attack, and to see that every thing was in good order. It is the pious conjecture of the learned bishop Patrick that he went into the valley alone, to pray to God for a blessing upon his enterprise, and he did not seek in vain. (5.) His constancy and perseverance; when he had stretched out his spear towards the city (Jos 8:18, a spear almost as fatal and formidable to the enemies of Israel as the rod of Moses was) he never drew back his hand till the work was done. His hands in fighting, like Moses's in interceding, were steady till the going down of the sun. Those that have stretched out their hands against their spiritual enemies must never draw them back. Lastly, What Joshua did in the stratagem is applicable to our Lord Jesus, of whom he was a type. Joshua conquered by yielding, as if he had himself been conquered; so our Lord Jesus, when he bowed his head and gave up the ghost, seemed as if death and triumphed over him, and as if he and all his interests had been routed and ruined; but in his resurrection he rallied again and gave the powers of darkness a total defeat; he broke the serpent's head, by suffering him to bruise his heel. A glorious stratagem!

2. What an obedient people Israel was. What Joshua commanded them to do, according to the commandment of the Lord (Jos 8:8), they did it without murmuring or disputing. Those that were sent to lie in ambush between Beth-el and Ai (two cities confederate against them) were in a post of danger, and had they been discovered might all have been cut off, and yet they ventured; and, when the body of the army retreated and fled, it was both disgraceful and perilous, and yet, in obedience to Joshua, they did it.

3. What an infatuated enemy the king of Ai was, (1.) That he did not by his scouts discover those that lay in ambush behind the city, Jos 8:14. Some observe it as a remarkable instance of the power of God in making men blind to their own interest, and the things that belong to their peace, that he wist not that there were liers in wait against him. Those are most in danger who are least aware that they are so. (2.) That when Israel seemed to fly he drew out all his forces to pursue them, and left none to guard his city and to secure his retreat, Jos 8:17. Thus the church's enemies often run themselves into destruction by their own fury and the violence of their rage against the Israel of God. Pharaoh plunged himself into the Red Sea by the eagerness with which he pursued Israel. (3.) That from the killing of thirty-six men out of 3000, when Israel made the former attack upon his city, he should infer the total routing of so great an army as now he had to deal with (Jos 8:6): They flee before us as at the first. See how the prosperity of fools destroys them and hardens them to their ruin. God had made use of the men of Ai as a scourge to chastise his people for meddling with the accursed thing, and this had puffed them up with a conceit that they must have the honour of delivering their country from these formidable invaders; but they were soon made to see their mistake, and that when the Israelites had reconciled themselves to their God they could have no power against them. God had made use of them only for the rebuking of Israel, with a purpose, when the correction was over, to throw the rod itself into the fire; howbeit, they meant not so, but it was in their heart to destroy and cut off, Isa 10:5-7.

4. What a complete victory Israel obtained over them by the favour and blessing of God. Each did his part: the divided forces of Israel, by signals agreed on, understood one another, and every thing succeeded according to the project; so that the men of Ai, even when they were most confident of victory, found themselves surrounded, so that they had neither spirit to resist nor room to fly, but were under a fatal necessity of yielding their lives to the destroyers. And now it is hard to say whether the shouts of the men of Israel, or the shrieks of the men of Ai, were the louder, but easy to imagine what terror and confusion they were filled with, when their highest assurances sunk so suddenly into the heaviest despair. Note, The triumphing of the wicked is short, Job 20:5. They are exalted for a little while, that their fall and ruin may be the sorer, Job 24:24. See how easily, how quickly, the scale turns against those that have not God on their side.

Tyndale Study Notes

On Joshua 8:3

8:3 set out to attack Ai: This first sentence provides a summary; details are filled in over the next several paragraphs. • The Hebrew words translated 30,000 might mean 30 units (see study note on Exod 12:37) or 30 chieftains. As the battle developed, this group would wait in ambush until Joshua called them out (Josh 8:18-19).
