Here we have the first mention of Noah, of whom we shall read much in the following chapters. Observe,

I.His name, with the reason of it: Noah signifies rest; his parents gave him that name, with a prospect of his being a more than ordinary blessing to his generation: This same shall comfort us concerning our work and toil of our hands, because of the ground which the Lord hath cursed. Here is, 1. Lamech's complaint of the calamitous state of human life. By the entrance of sin, and the entail of the curse for sin, our condition has become very miserable: our whole life is spent in labour, and our time filled up with continual toil. God having cursed the ground, it is as much as some can do, with the utmost care and pains, to fetch a hard livelihood out of it. He speaks as one fatigued with the business of this life, and grudging that so many thoughts and precious minutes, which otherwise might have been much better employed, are unavoidably spent for the support of the body. 2. His comfortable hopes of some relief by the birth of this son: This same shall comfort us, which denotes not only the desire and expectation which parents generally have concerning their children (that, when they grow up, they will be comforts to them and helpers in their business, though they often prove otherwise), but an apprehension and prospect of something more. Very probably there were some prophecies that went before of him, as a person that should be wonderfully serviceable to his generation, which they so understood as to conclude that he was the promised seed, the Messiah that should come; and then it intimates that a covenant-interest in Christ as ours, and the believing expectation of his coming, furnish us with the best and surest comforts, both in reference to the wrath and curse of God which we have deserved and to the toils and troubles of this present time of which we are often complaining. "Is Christ ours? Is heaven ours? This same shall comfort us."

II.His children, Shem, Ham, and Japheth. These Noah begat (the eldest of these) when he was 500 years old. It should seem that Japheth was the eldest (Gen 10:21), but Shem is put first because on him the covenant was entailed, as appears by Gen 9:26, where God is called the Lord God of Shem. To him, it is probable, the birth-right was given, and from him, it is certain, both Christ the head, and the church the body, were to descend. Therefore he is called Shem, which signifies a name, because in his posterity the name of God should always remain, till he should come out of his loins whose name is above every name; so that in putting Shem first Christ was, in effect, put first, who in all things must have the pre-eminence.

The days of Methuselah were nine hundred sixty and nine years - This is the longest life mentioned in Scripture, and probably the longest ever lived; but we have not authority to say positively that it was the longest. Before the flood, and before artificial refinements were much known and cultivated, the life of man was greatly protracted, and yet of him who lived within thirty-one years of a thousand it is said he died; and the longest life is but as a moment when it is past. Though life is uncertain, precarious, and full of natural evils, yet it is a blessing in all its periods if devoted to the glory of God and the interest of the soul; for while it lasts we may more and more acquaint ourselves with God and be at peace, and thereby good shall come unto us; Job 22:21.

And Noah was five hundred years old,.... Or "the son of five hundred years" (f); he was in his five hundredth year: it can hardly be thought that he should live to this time a single life, and have no children born to him, which he might have had, but were dead; though some think it was so ordered by Providence, that he should not begin to procreate children until of this age, because it being the will of God to save him and his family from the flood, had he began at the usual age he might have had more than could conveniently be provided for in the ark; or some of them might have proved wicked, and so would deserve to perish with others:

and Noah begat Shem, Ham, and Japheth; not together, but one after another; and since Ham was the younger son, see Gen 9:24 and Shem was an hundred years old two years after the flood, Gen 11:10 he must be born in the five hundred and second year of his father's age; so that it seems most probable that Japheth was the eldest son, and born in the five hundred and first year of his age; though Shem is usually mentioned first, because of his superior dignity and excellency, God being in an eminent manner the God of Shem, Gen 9:26 and from whom the Messiah was to spring, and in whose line the church of God was to be continued in future ages. The name of Japheth is retained in Greek and Latin authors, as Hesiod (g) Horace (h), and others (i), by whom he is called Japetos and Japetus.

Next: Genesis Chapter 6

Lamech--a different person from the one mentioned in the preceding chapter [Gen 4:18]. Like his namesake, however, he also spoke in numbers on occasion of the birth of Noah--that is, "rest" or "comfort" [Gen 5:29, Margin]. "The allusion is, undoubtedly, to the penal consequences of the fall in earthly toils and sufferings, and to the hope of a Deliverer, excited by the promise made to Eve. That this expectation was founded on a divine communication we infer from the importance attached to it and the confidence of its expression" [PETER SMITH].
