On Exodus 18:1-5

VISIT OF JETHRO. (Exo. 18:1-27)

Jethro . . . came . . . unto Moses, &c. - It is thought by many eminent commentators that this episode is inserted out of its chronological order, for it is described as occurring when the Israelites were "encamped at the mount of God." And yet they did not reach it till the third month after their departure from Egypt (Exo 19:1-2; compare Deu 1:6, Deu 1:9-15).

John Gill

On Exodus 18:1

When Jethro the priest of Midian, Moses's father-in-law,.... The Targums of Onkelos and Jonathan call him the prince of Midian, and so the word (e) is rendered in some versions; whose daughter Moses had married, and so was his father-in-law, of which see more in Exodus 2:16.

heard of all that God had done for Moses, and for Israel his people; the miracles he had wrought for them in Egypt, the dividing of the Red sea to make a way for them, the destruction of the Egyptians, providing them with bread and water in such a miraculous manner in the wilderness, and giving them victory over Amalek, and appearing always at the head of them in a pillar of cloud and fire:

and that the Lord had brought Israel out of Egypt: which was the greatest blessing of all, and for the sake of which so many wonderful things had been done to Pharaoh and the Egyptians. And now Midian being near to Egypt, it is not to be wondered at that Jethro should hear of these things, the fame of which went through all the countries round about, see Exodus 15:14, though it is not improbable that Moses might send messengers to Midian to acquaint his father-in-law, his wife, and sons, of what the Lord had done for him, and by him.

Keil & Delitzsch

On Exodus 18:1-5

The Amalekites had met Israel with hostility, as the prototype of the heathen who would strive against the people and kingdom of God. But Jethro, the Midianitish priest, appeared immediately after in the camp of Israel, not only as Moses' father-in-law, to bring back his wife and children, but also with a joyful acknowledgement of all that Jehovah had done to the Israelites in delivering them from Egypt, to offer burnt-offerings to the God of Israel, and to celebrate a sacrificial meal with Moses, Aaron, and all the elders of Israel; so that in the person of Jethro the first-fruits of the heathen, who would hereafter seek the living God, entered into religious fellowship with the people of God. As both the Amalekites and Midianites were descended from Abraham, and stood in blood-relationship to Israel, the different attitudes which they assumed towards the Israelites foreshadowed and typified the twofold attitude which the heathen world would assume towards the kingdom of God. (On Jethro, see Exo 2:18; on Moses' wife and sons, see Exo 2:21-22; and on the expression in Exo 18:2, "after he had sent her back," Exo 4:26.) - Jethro came to Moses "into the wilderness, where he encamped at the mount of God." The mount of God is Horeb (Exo 3:1); and the place of encampment is Rephidim, at Horeb, i.e., at the spot where the Sheikh valley opens into the plain of er Rahah (Exo 17:1). This part is designated as a wilderness; and according to Robinson (1, pp. 130, 131) the district round this valley and plain is "naked desert," and "wild and desolate." The occasion for Jethro the priest to bring back to his son-in-law his wife and children was furnished by the intelligence which had reached him, that Jehovah had brought Israel out of Egypt (Exo 18:1), and, as we may obviously supply, had led them to Horeb. When Moses sent his wife and sons back to Jethro, he probably stipulated that they were to return to him on the arrival of the Israelites at Horeb. For when God first called Moses at Horeb, He foretold to him that Israel would be brought to this mountain on its deliverance from Egypt (Exo 3:12).

(Note: Kurtz (Hist. of O. C. iii. 46, 53) supposes that it was chiefly the report of the glorious result of the battle with Amalek which led Jethro to resolve to bring Moses' family back to him. There is no statement, however, to this effect in the biblical text, but rather the opposite, namely, that what Jethro had heard of all that God had done to Moses and Israel consisted of the fact that Jehovah had brought Israel out of Egypt. Again, there are not sufficient grounds for placing the arrival of Jethro at the camp of Israel, in the desert of Sinai and after the giving of the law, as Ranke has done. For the fact that the mount of God is mentioned as the place of encampment at the time, is an argument in favour of Rephidim, rather than against it, as we have already shown. And we can see no force in the assertion that the circumstances, in which we find the people, point rather to the longer stay at Sinai, than to the passing halt at Rephidim. For how do we know that the stay at Rephidim was such a passing one, that it would not afford time enough for Jethro's visit? It is true that, according to the ordinary assumption, only half a month intervened between the arrival of the Israelites in the desert of Sin and their arrival in the desert of Sinai; but within this space of time everything might have taken place that is said to have occurred on the march from the former to the latter place of encampment. It is not stated in the biblical text that seven days were absorbed in the desert of Sin alone, but only that the Israelites spent a Sabbath there, and had received manna a few days before, so that three or four days (say from Thursday to Saturday inclusive) would amply suffice for all that took place. If the Israelites, therefore, encamped there in the evening of the 15th, they might have moved farther on the morning of the 19th or 20th, and after a two days' journey by Dofkah and Alush have reached Rephidim on the 21st or 22nd. They could then have fought the battle with the Amalekites the following day, so that Jethro might have come to the camp on the 24th or 25th, and held the sacrificial meal with the Israelites the next day. In that case there would still be four or five days left for him to see Moses sitting in judgment a whole day long (Exo 18:13), and for the introduction of the judicial arrangements proposed by Jethro; - amply sufficient time, inasmuch as one whole day would suffice for the sight of the judicial sitting, which is said to have taken place the day after the sacrificial meal (Exo 18:13). And the election of judges on the part of the people, for which Moses gave directions in accordance with Jethro's advice, might easily have been carried out in two days. For, on the one hand, it is most probable that after Jethro had watched this severe and exhausting occupation of Moses for a whole day, he spoke to Moses on the subject the very same evening, and laid his plan before him; and on the other hand, the execution of this plan did not require a very long time, as the people were not scattered over a whole country, but were collected together in one camp. Moreover, Moses carried on all his negotiations with the people through the elders as their representatives; and the judges were not elected in modern fashion by universal suffrage, but were nominated by the people, i.e., by the natural representatives of the nation, from the body of elders, according to their tribes, and then appointed by Moses himself. - Again, it is by no means certain that Israel arrived at the desert of Sinai on the first day of the third month, and that only half a month (15 or 16 days) elapsed between their arrival in the desert of sin and their encamping at Sinai (cf. Exo 19:1). And lastly, though Kurtz still affirms that Jethro lived on the other side of the Elanitic Gulf, and did not set out till he heard of the defeat of the Amalekites, in which case a whole month might easily intervene between the victory of Israel and the arrival of Jethro, the two premises upon which this conclusion is based, are assumptions without foundation, as we have already shown at Exo 3:1 in relation to the former, and have just shown in relation to the latter.)

Matthew Henry

On Exodus 18:1-6

This incident may very well be allowed to have happened as it is placed here, before the giving of the law, and not, as some place it, in connection with what is recorded, Num 10:11, Num 10:29, etc. Sacrifices were offered before; in these mentioned here (Exo 18:12) it is observable that Jethro is said to take them, not Aaron. And as to Jethro's advising Moses to constitute judges under him, though it is intimate (Exo 18:13) that the occasion of his giving that advice was on the morrow, yet it does not follow but that Moses's settlement of that affair might be some time after, when the law was given, as it is placed, Deu 1:9. It is plain that Jethro himself would not have him make this alteration in the government till he had received instructions from God about it (Exo 18:23), which he did not till some time after. Jethro comes,

I. To congratulate the happiness of Israel, and particularly the honour of Moses his son-in-law; and now Jethro thinks himself well paid for all the kindness he had shown to Moses in his distress, and his daughter better matched than he could have expected. Jethro could not but hear what all the country rang of, the glorious appearances of God for his people Israel (Exo 18:1); and he comes to enquire, and inform himself more fully thereof (see Psa 111:2), and to rejoice with them as one that had a true respect both for them and for their God. Though he, as a Midianite, was not to share with them in the promised land, yet he shared with them in the joy of their deliverance. We may thus make the comforts of others our own, by taking pleasure, as God does, in the prosperity of the righteous.

II. To bring Moses's wife and children to him. It seems, he had sent them back, probably from the inn where his wife's aversion to the circumcision of her son had like to have cost him his life (Exo 4:25); fearing lest they should prove a further hindrance, he sent them home to his father-in-law. He foresaw what discouragements he was likely to meet with in the court of Pharaoh, and therefore would not take any with him in his own family. He was of that tribe that said to his father, I have not known him, when service was to be done for God, Deu 33:9. Thus Christ's disciples, when they were to go upon an expedition not much unlike that of Moses, were to forsake wife and children, Mat 19:29. But though there might be reason for the separation that was between Moses and his wife for a time, yet they must come together again, as soon as ever they could with any convenience. It is the law of the relation. You husbands, dwell with your wives, Pe1 3:7. Jethro, we may suppose, was glad of his daughter's company, and fond of her children, yet he would not keep her from her husband, nor them from their father, Exo 18:5, Exo 18:6. Moses must have his family with him, that while he ruled the church of God he might set a good example of prudence in family-government, Ti1 3:5. Moses had now a great deal both of honour and care put upon him, and it was fit that his wife should be with him to share with him in both. Notice is taken of the significant names of his two sons. 1. The eldest was called Gershom (Exo 18:3), a stranger, Moses designing thereby, not only a memorial of his own condition, but a memorandum to his son of his condition also: for we are all strangers upon earth, as all our fathers were. Moses had a great uncle almost of the same name, Gershon, a stranger; for though he was born in Canaan (Gen 46:11), yet even there the patriarchs confessed themselves strangers. 2. The other he called Eliezer (Exo 18:4), My God a help, as we translate it; it looks back to his deliverance from Pharaoh, when he made his escape, after the slaying of the Egyptian; but, if this was (as some think) the son that was circumcised at the inn as he was going, I would rather translate it so as to look forward, which the original will bear, The Lord is my help, and will deliver me from the sword of Pharaoh, which he had reason to expect would be drawn against him when he was going to fetch Israel out of bondage. Note, When we are undertaking any difficult service for God and our generation, it is good for us to encourage ourselves in God as our help: he that has delivered does and will deliver.

Tyndale Study Notes

On Exodus 18:1-6

18:1-12 Moses had apparently sent his wife and children back from Egypt at some point to stay with his father-in-law. In the intense confrontation with Pharaoh, Moses might have been afraid for their lives. Jethro now came to meet Moses and the Israelites, bringing Moses’ family with him (18:2-6). In the context of the visit, Moses gave him a report, and Jethro was brought to faith through the testimony of the Lord’s work.
