Adam Clarke

On Genesis 8:20

Noah builded an altar - As we have already seen that Adam, Cain, and Abel, offered sacrifices, there can be no doubt that they had altars on which they offered them; but this, builded by Noah, is certainly the first on record. It is worthy of remark that, as the old world began with sacrifice, so also did the new. Religion or the proper mode of worshipping the Divine Being, is the invention or institution of God himself; and sacrifice, in the act and design, is the essence of religion. Without sacrifice, actually offered or implied, there never was, there never can be, any religion. Even in the heavens, a lamb is represented before the throne of God as newly slain, Rev 5:6, Rev 5:12, Rev 5:13. The design of sacrificing is two-fold: the slaying and burning of the victim point out, 1st, that the life of the sinner is forfeited to Divine justice; 2dly, that his soul deserves the fire of perdition.

The Jews have a tradition that the place where Noah built his altar was the same in which the altar stood which was built by Adam, and used by Cain and Abel, and the same spot on which Abraham afterwards offered up his son Isaac.

The word מזבח mizbach, which we render altar, signifies properly a place for sacrifice, as the root זבח zabach signifies simply to slay. Altar comes from the Latin altus, high or elevated, because places for sacrifice were generally either raised very high or built on the tops of hills and mountains; hence they are called high places in the Scriptures; but such were chiefly used for idolatrous purposes.

Burnt-offerings - See the meaning of every kind of offering and sacrifice largely explained on Leviticus 7:1-38.

Jamieson, Fausset & Brown

On Genesis 8:20

Noah builded an altar - literally, "a high place"--probably a mound of earth, on which a sacrifice was offered. There is something exceedingly beautiful and interesting to know that the first care of this devout patriarch was to return thanks for the signal instance of mercy and goodness which he and his family had experienced.

took of every clean beast . . . fowl - For so unparalleled a deliverance, a special acknowledgment was due.

John Gill

On Genesis 8:20

And Noah builded an altar unto the Lord,.... Not an house for himself and his family, but an altar for God; his first and greatest concern being for the glory of God, and not for the temporal good of himself and his: this altar was erected, and devoted to the service of God; it was built according to his will, and by his direction: Noah's view was to renew the worship of God, preserve and propagate it by his example; and this was done by way of thanksgiving to God for his wonderful preservation of him, and was also propitiatory and typical of Christ: the Jewish writers (d) say, this was the altar on which Adam sacrificed, when expelled the garden of Eden, and on which Cain and Abel offered; and being demolished by the flood, was rebuilt by Noah, which is not at all probable; it is much more likely what Aben Ezra says, that it was built on one of the mountains of Ararat, and that as Noah took the first opportunity, so he built it in the first place he came to, or at least not far from the place where he came out of the ark:

and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar; the clean beasts were the bullock, the sheep, and goat, and the clean fowl, the turtle and young pigeon, one of each sort at least was taken. The Targum of Jonathan says, he offered four upon the altar: these were typical of Christ; the bullock or heifer might denote his strength, the sheep or lamb his patience and harmlessness, the turtle or dove his meekness; and being burnt offerings, may signify the painful and dolorous sufferings of Christ, when the wrath of God was poured on him like fire.

Keil & Delitzsch

On Genesis 8:20-22

The first thing which Noah did, was to build an altar for burnt sacrifice, to thank the Lord for gracious protection, and pray for His mercy in time to come. This altar - מזבּח, lit., a place for the offering of slain animals, from זבח, like θυσιαστήριον from θύειν - is the first altar mentioned in history. The sons of Adam had built no altar for their offerings, because God was still present on the earth in paradise, so that they could turn their offerings and hearts towards that abode. But with the flood God had swept paradise away, withdrawn the place of His presence, and set up His throne in heaven, from which He would henceforth reveal Himself to man (cf. Gen 9:5, Gen 9:7). In future, therefore, the hearts of the pious had to be turned towards heaven, and their offerings and prayers needed to ascend on high if they were to reach the throne of God. To give this direction to their offerings, heights or elevated places were erected, from which they ascended towards heaven in fire. From this the offerings received the name of עלת from עולה, the ascending, not so much because the sacrificial animals ascended or were raised upon the altar, as because they rose from the altar to haven (cf. Jdg 20:40; Jer 48:15; Amo 4:10). Noah took his offerings from every clean beast and every clean fowl - from those animals, therefore, which were destined for man's food; probably the seventh of every kind, which he had taken into the ark. "And Jehovah smelled the smell of satisfaction," i.e., He graciously accepted the feelings of the offerer which rose to Him in the odour of the sacrificial flame. In the sacrificial flame the essence of the animal was resolved into vapour; so that when man presented a sacrifice in his own stead, his inmost being, his spirit, and his heart ascended to God in the vapour, and the sacrifice brought the feeling of his heart before God. This feeling of gratitude for gracious protection, and of desire for further communications of grace, was well-pleasing to God. He "said to His heart' (to, or in Himself; i.e., He resolved), "I will not again curse the ground any more for man's sake, because the image (i.e., the thought and desire) of man's heart is evil from his youth up (i.e., from the very time when he begins to act with consciousness)." This hardly seems an appropriate reason. As Luther says: "Hic inconstantiae videtur Deus accusari posse. Supra puniturus hominem causam consilii dicit, quia figmentum cordis humani malum est. Hic promissurus homini gratiam, quod posthac tali ira uti nolit, eandem causam allegat." Both Luther and Calvin express the same thought, though without really solving the apparent discrepancy. It was not because the thoughts and desires of the human heart are evil that God would not smite any more every living thing, that is to say, would not exterminate it judicially; but because they are evil from his youth up, because evil is innate in man, and for that reason he needs the forbearance of God; and also (and here lies the principal motive for the divine resolution) because in the offering of the righteous Noah, not only were thanks presented for past protection, and entreaty for further care, but the desire of man was expressed, to remain in fellowship with God, and to procure the divine favour. "All the days of the earth;" i.e., so long as the earth shall continue, the regular alternation of day and night and of the seasons of the year, so indispensable to the continuance of the human race, would never be interrupted again.

Matthew Henry

On Genesis 8:20-22

Here is, I. Noah's thankful acknowledgment of God's favour to him, in completing the mercy of his deliverance, Gen 8:20. 1. He built an altar. Hitherto he had done nothing without particular instructions and commands from God. He had a particular call into the ark, and another out of it; but, altars and sacrifices being already of divine institution for religious worship, he did not stay for a particular command thus to express his thankfulness. Those that have received mercy from God should be forward in returning thanks, and do it not of constraint, but willingly. God is pleased with free-will offerings, and praises that wait for him. Noah was now turned out into a cold and desolate world, where, one would have thought, his first care would have been to build a house for himself; but, behold, he begins with an altar for God: God, that is the first, must be first served; and he begins well that begins with God. 2. He offered a sacrifice upon his altar, of every clean beast, and of every clean fowl - one, the odd seventh that we read of, Gen 7:2, Gen 7:3. Here observe, (1.) He offered only those that were clean; for it is not enough that we sacrifice, but we must sacrifice that which God appoints, according to the law of sacrifice, and not a corrupt thing. (2.) Though his stock of cattle was so small, and that rescued from ruin at so great an expense of care and pains, yet he did not grudge to give God his dues out of it. He might have said, "Have I but seven sheep to begin the world with, and must one of these seven be killed and burnt for sacrifice? Were it not better to defer it till we have greater plenty?" No, to prove the sincerity of his love and gratitude, he cheerfully gives the seventh to his God, as an acknowledgment that all was his, and owing to him. Serving God with our little is the way to make it more; and we must never think that wasted with which God is honoured. (3.) See here the antiquity of religion: the first thing we find done in the new world was an act of worship, Jer 6:16. We are now to express our thankfulness, not by burnt-offerings, but by the sacrifices of praise and the sacrifices of righteousness, by pious devotions and a pious conversation.

II. God's gracious acceptance of Noah's thankfulness. It was a settled rule in the patriarchal age: If thou doest well, shalt thou not be accepted? Noah was so. For,

1. God was well pleased with the performance, Gen 8:21. He smelt a sweet savour, or, as it is in the Hebrew, a savour of rest, from it. As, when he had made the world at first on the seventh day, he rested and was refreshed, so, now that he had new-made it, in the sacrifice of the seventh he rested. He was well pleased with Noah's pious zeal, and these hopeful beginnings of the new world, as men are with fragrant and agreeable smells; though his offering was small it was according to his ability, and God accepted it. Having caused his anger to rest upon the world of sinners, he here caused his love to rest upon this little remnant of believers.

2. Hereupon, he took up a resolution never to drown the world again. Herein he had an eye, not so much to Noah's sacrifice as to Christ's sacrifice of himself, which was typified and represented by it, and which was indeed an offering of a sweet-smelling savour, Eph 5:2. Good security is here given, and that which may be relied upon,

(1.) That this judgment should never be repeated. Noah might think, "To what purpose should the world be repaired, when, in all probability, for the wickedness of it, it will quickly be in like manner ruined again?" "No," says God, "it never shall." It was said (Gen 6:6), It repented the Lord that he had made man; now here he speaks as if it repented him that he had destroyed man: neither means a change of his mind, but both a change of his way. It repented him concerning his servants, Deu 32:36. Two ways this resolve is expressed: - [1.] I will not again curse the ground, Heb. I will not add to curse the ground any more. God had cursed the ground upon the first entrance of sin (Gen 3:17), when he drowned it he added to that curse; but now he determines not to add to it any more. [2.] Neither will I again smite any more every living thing; that is, it was determined that whatever ruin God might bring upon particular persons, or families, or countries, he would never again destroy the whole world till the day shall come when time shall be no more. But the reason of this resolve is very surprising, for it seems the same in effect with the reason given for the destruction of the world: Because the imagination of man's heart is evil from his youth, Gen 6:5. But there is this difference - there it is said, The imagination of man's heart is evil continually, that is, "his actual transgressions continually cry against him;" here it is said, It is evil from his youth or childhood. It is bred in the bone; he brought it into the world with him; he was shapen and conceived in it. Now, one would think it should follow, "Therefore that guilty race shall be wholly extinguished, and I will make a full end." No, "Therefore I will no more take this severe method; for," First, "He is rather to be pitied, for it is all the effect of sin dwelling in him; and it is but what might be expected from such a degenerate race: he is called a transgressor from the womb, and therefore it is not strange that he deals so very treacherously," Isa 48:8. Thus God remembers that he is flesh, corrupt and sinful, Psa 78:39. Secondly, "He will be utterly ruined; for, if he be dealt with according to his deserts, one flood must succeed another till all be destroyed." See here, 1. That outward judgments, though they may terrify and restrain men, yet cannot of themselves sanctify and renew them; the grace of God must work with those judgments. Man's nature was as sinful after the deluge as it had been before. 2. That God's goodness takes occasion from man's sinfulness to magnify itself the more; his reasons of mercy are all drawn from himself, not from any thing in us.

(2.) That the course of nature should never be discontinued (Gen 8:22): "While the earth remaineth, and man upon it, there shall be summer and winter (not all winter as had been this last year), day and night," not all night, as probably it was while the rain was descending. Here, [1.] It is plainly intimated that this earth is not to remain always; it, and all the works in it, must shortly be burnt up; and we look for new heavens and a new earth, when all these things must be dissolved. But, [2.] As long as it does remain God's providence will carefully preserve the regular succession of times and seasons, and cause each to know its place. To this we owe it that the world stands, and the wheel of nature keeps it track. See here how changeable the times are and yet how unchangeable. First, The course of nature always changing. As it is with the times, so it is with the events of time, they are subject to vicissitudes - day and night, summer and winter, counterchanged. In heaven and hell it is not so, but on earth God hath set the one over against the other. Secondly, Yet never changed. It is constant in this inconstancy. These seasons have never ceased, nor shall cease, while the sun continued such a steady measurer of time and the moon such a faithful witness in heaven. This is God's covenant of the day and of the night, the stability of which is mentioned for the confirming of our faith in the covenant of grace, which is no less inviolable, Jer 33:20, Jer 33:21. We see God's promises to the creatures made good, and thence may infer that his promises to all believers shall be so.

Tyndale Study Notes

On Genesis 8:20

8:20 This first mention of an altar in the Bible shows Noah’s gratitude for having passed through the judgment. • sacrificed as burnt offerings: The same wording is used of the whole burnt offering in Leviticus (Lev 1:3-9); however, it can refer to any offering that is burned. Noah gave this offering to thank and worship God, who had delivered him and his family from the flood.
