Genesis 9:7
Ver. 7. And you, be ye fruitful and multiply,.... Instead of taking away the lives of men, the great concern should be to multiply them; and this indeed is one reason of the above law, to prevent the decrease and ruin of mankind; and which was peculiarly needful, when there were so few men in the world as only four, and therefore it is repeated in stronger terms:
bring forth abundantly in the earth, and multiply therein; that the whole earth might be overspread with men, and repeopled sufficiently, as it was by the sons of Noah, see Ge 9:19.
