This is the book of the generations of Adam. In the day when God created man, He made him in the likeness of God.
He created them male and female, and He blessed them and named them Man in the day when they were created. When Adam had lived one hundred and thirty years, he became the father of a son in his own likeness, according to his image, and named him Seth.
Then the days of Adam after he became the father of Seth were eight hundred years, and he had other sons and daughters. So all the days that Adam lived were nine hundred and thirty years, and he died.
Genesis 5 : 1 – 5 (New American Standard Bible)
“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.”#
