The first words of the chapter are the title or argument of the whole chapter: it is the book of the generations of Adam; it is the list or catalogue of the posterity of Adam, not of all, but only of the holy seed who were the substance thereof (Isa 6:13), and of whom, as concerning the flesh, Christ came (Rom 9:5), the names, ages, and deaths, of those that were the successors of the first Adam in the custody of the promise, and the ancestors of the second Adam. The genealogy begins with Adam himself. Here is,

I.His creation, Gen 5:1, Gen 5:2, where we have a brief rehearsal of what was before at large related concerning the creation of man. This is what we have need frequently to hear of and carefully to acquaint ourselves with. Observe here, 1. That God created man. Man is not his own maker, therefore he must not be his own master; but the Author of his being must be the director of his motions and the centre of them. 2. That there was a day in which God created man. He was not from eternity, but of yesterday; he was not the first-born, but the junior of the creation. 3. That God made him in his own likeness, righteous and holy, and therefore, undoubtedly, happy. Man's nature resembled the divine nature more than that of any of the creatures of this lower world. 4. That God created them male and female (Gen 5:2), for their mutual comfort as well as for the preservation and increase of their kind. Adam and Eve were both made immediately by the hand of God, both made in God's likeness; and therefore between the sexes there is not that great distance and inequality which some imagine. 5. That God blessed them. It is usual for parents to bless their children; so God, the common Father, blessed his. But earthly parents can only beg a blessing; it is God's prerogative to command it. It refers chiefly to the blessing of increase, not excluding other blessings. 6. That he called their name Adam. Adam signifies earth, red earth. Now, (1.) God gave him this name. Adam had himself named the rest of the creatures, but he must not choose his own name, lest he should assume some glorious pompous title. But God gave him a name which would be a continual memorandum to him of the meanness of his original, and oblige him to look unto the rock whence he was hewn and the hole of the pit whence he was digged, Isa 51:1. Those have little reason to be proud who are so near akin to dust. (2.) He gave this name both to the man and to the woman. Being at first one by nature, and afterwards one by marriage, it was fit they should both have the same name, in token of their union. The woman is of the earth earthy as well as the man.

II.The birth of his son Seth, Gen 5:3. He was born in the hundred and thirtieth year of Adam's life; and probably the murder of Abel was not long before. Many other sons and daughters were born to Adam, besides Cain and Abel, before this; but no notice is taken of them, because an honourable mention must be made of his name only in whose loins Christ and the church were. But that which is most observable here concerning Seth is that Adam begat him in his own likeness, after his image. Adam was made in the image of God; but, when he was fallen and corrupt, he begat a son in his own image, sinful and defiled, frail, mortal, and miserable, like himself; not only a man like himself, consisting of body and soul, but a sinner like himself, guilty and obnoxious, degenerate and corrupt. Even the man after God's own heart owns himself conceived and born in sin, Psa 51:5. This was Adam's own likeness, the reverse of that divine likeness in which Adam was made; but, having lost it himself, he could not convey it to his seed. Note, Grace does not run in the blood, but corruption does. A sinner begets a sinner, but a saint does not beget a saint.

III.His age and death. He lived, in all, nine hundred and thirty years, and then he died, according to the sentence passed upon him, To dust thou shalt return. Though he did not die in the day he ate forbidden fruit, yet in that very day he became mortal. Then he began to die; his whole life afterwards was but a reprieve, a forfeited condemned life; nay, it was a wasting dying life: he was not only like a criminal sentenced, but as one already crucified, that dies slowly and by degrees.

And Adam lived a hundred and thirty years, etc. - The Scripture chronology especially in the ages of some of the antediluvian and postdiluvian patriarchs, has exceedingly puzzled chronologists, critics, and divines. The printed Hebrew text, the Samaritan, the Septuagint, and Josephus, are all different, and have their respective vouchers and defenders. The following tables of the genealogies of the patriarchs before and after the flood, according to the Hebrew, Samaritan, and Septuagint, will at once exhibit the discordances. For much satisfactory information on this subject I must refer to A New Analysis of Chronology, by the Rev. William Hales, D.D., 3 vols. 4th., London, 1809.

And begat a son in his own likeness, after his image - Words nearly the same with those Gen 1:26 : Let us make man in our image, after our likeness. What this image and likeness of God were, we have already seen, and we may rest assured that the same image and likeness are not meant here. The body of Adam was created provisionally immortal, i.e. while he continued obedient he could not die; but his obedience was voluntary, and his state a probationary one. The soul of Adam was created in the moral image of God, in knowledge, righteousness, and true holiness. He had now sinned, and consequently had lost his moral resemblance to his Maker; he had also become mortal through his breach of the law. His image and likeness were therefore widely different at this time from what they were before; and his begetting children in this image and likeness plainly implies that they were imperfect like himself, mortal like himself, sinful and corrupt like himself. For it is impossible that he, being impure, fallen from the Divine image, could beget a pure and holy offspring, unless we could suppose it possible that a bitter fountain could send forth sweet waters, or that a cause could produce effects totally dissimilar from itself. What is said here of Seth might have been said of all the other children of Adam, as they were all begotten after his fall; but the sacred writer has thought proper to mark it only in this instance.

And the days of Adam, after he had begotten Seth, were eight hundred years,.... The Septuagint version is seven hundred; for having added one hundred years more the should be, to the years of his life before the birth of Seth, here they are taken away to make the number of his years complete:

and he begat sons and daughters; not only after the birth of Seth, but before, though we have no account of any, unless of Cain's wife; but what their number was is not certain, either before or after; some say he had thirty children, besides Cain, Abel, and Seth; and others a hundred (c). Josephus says the number of children, according to the old tradition, was thirty three sons and twenty three daughters. (d)(These families had at least five children, for one son is named as well as other sons and daughters. Therefore there must be at least three sons and two daughters in each family. For a family to have at least three sons and two daughters, according to the laws of chance, a family must on the average have nine children for this to be a near certainty. Hence the families listed in this chapter must have been large by today's standards. Given their long life, this is not at all unusual. However even today, the Old Order Mennonites of Waterloo County in Ontario and Lancaster County in Pennsylvannia, have many families this large. Ed.)
