51 This is the book of the generations of Adam. In the day when God made man, he made him in the image of God; 2 Male and female he made them, naming them Man, and giving them his blessing on the day when they were made. 3 Adam had been living for a hundred and thirty years when he had a son like himself, after his image, and gave him the name of Seth:
Matthew Henry's Commentary on Genesis 5:1-3
Commentary on Genesis 5:1-5
(Read Genesis 5:1-5)
Adam was made in the image of God; but when fallen he begat a son in his own image, sinful and defiled, frail, wretched, and mortal, like himself. Not only a man like himself, consisting of body and soul, but a sinner like himself. This was the reverse of that Divine likeness in which Adam was made; having lost it, he could not convey it to his seed. Adam lived, in all, 930 years; and then 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 after was but a reprieve, a forfeited, condemned life; it was a wasting, dying life. Man's life is but dying by degrees.
