Genesis 6:18-22

But I will establish my covenant with thee; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons’ wives with thee. And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female. Of the birds after their kind, and of the cattle after their kind, of every creeping thing of the ground after its kind, two of every sort shall come unto thee, to keep them alive. And take thou unto thee of all food that is eaten, and gather it to thee; and it shall be for food for thee, and for them. Thus did Noah; according to all that God commanded him, so did he.
