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.

We have here all that the Holy Ghost thought fit to leave upon record concerning five of the patriarchs before the flood, Seth, Enos, Cainan, Mahalaleel, and Jared. There is nothing observable concerning any of these particularly, though we have reason to think they were men of eminence, both for prudence and piety, in their day: but in general, I. Observe how largely and expressly their generations are recorded. This matter, one would think, might have been delivered in fewer words; but it is certain that there is not one idle word in God's books, whatever there is in men's. It is thus plainly set down, 1. To make it easy and intelligible to the meanest capacity. When we are informed how old they were when they begat such a son, and how many years they lived afterwards, a very little skill in arithmetic will enable a man to tell how long they lived in all; yet the Holy Ghost sets down the sum total, for the sake of those that have not even so much skill as this. 2. To show the pleasure God takes in the names of his people. We found Cain's generation numbered in haste (Gen 4:18), but this account of the holy seed is enlarged upon, and given in words at length, and not in figures; we are told how long those lived that lived in God's fear, and when those died that died in his favour; but as for others it is no matter. The memory of the just is blessed, but the name of the wicked shall rot. II. Their life is reckoned by days (Gen 5:8): All the days of Seth, and so of the rest, which intimates the shortness of the life of man when it is at the longest, and the quick revolution of our times on earth. If they reckoned by days, surely we must reckon by hours, or rather make that our frequent prayer (Psa 90:12), Teach us to number our days. III. Concerning each of them, except Enoch, it is said, and he died. It is implied in the numbering of the years of their life that their life, when those years were numbered and finished, came to an end; and yet it is still repeated, and he died, to show that death passed upon all men without exception, and that it is good for us particularly to observe and improve the deaths of others for our own edification. Such a one was a strong healthful man, but he died; such a one was a great and rich man, but he died; such a one was a wise politic man, but he died; such a one was a very good man, perhaps a very useful man, but he died, etc. IV. That which is especially observable is that they all lived very long; not one of them died till he had seen the revolution of almost eight hundred years, and some of them lived much longer, a great while for an immortal soul to be imprisoned in a house of clay. The present life surely was not to them such a burden as commonly it is now, else they would have been weary of it; nor was the future life so clearly revealed then as it is now under the gospel, else they would have been impatient to remove to it: long life to the pious patriarchs was a blessing and made them blessings. 1. Some natural causes may be assigned for their long life in those first ages of the world. It is very probable that the earth was more fruitful, that the productions of it were more strengthening, that the air was more healthful, and that the influences of the heavenly bodies were more benign, before the flood, than afterwards. Though man was driven out of paradise, yet the earth itself was then paradisiacal - a garden in comparison with its present wilderness-state: and some think that their great knowledge of the creatures, and of their usefulness both for food and medicine, together with their sobriety and temperance, contributed much to it; yet we do not find that those who were intemperate, as many were (Luk 17:27), were as short-lived as intemperate men generally are now. 2. It must chiefly be resolved into the power and providence of God. He prolonged their lives, both for the more speedy replenishing of the earth and for the more effectual preservation of the knowledge of God and religion, then, when there was no written word, but tradition was the channel of its conveyance. All the patriarchs here, except Noah, were born before Adam died; so that from him they might receive a full and satisfactory account of the creation, paradise, the fall, the promise, and those divine precepts which concerned religious worship and a religious life: and, if any mistake arose, they might have recourse to him while he lived, as to an oracle, for the rectifying of it, and after his death to Methuselah, and others, that had conversed with him: so great was the care of Almighty God to preserve in his church the knowledge of his will and the purity of his worship.
