And it came to pass that after I, the Lord God, had driven them out, that Adam began to till the earth, and to have dominion over all the beasts of the field, and to eat his bread by the sweat of his brow, as I the Lord had commanded him. And Eve, also, his wife, did labor with him.
And Adam knew his wife, and she bare unto him sons and daughters, and they began to multiply and to replenish the earth.
And from that time forth, the sons and daughters of Adam began to divide two and two in the land, and to till the land, and to tend flocks, and they also begat sons and daughters.
