Genesis 6:18-22

But I will establish My covenant (solemn promise, formal agreement) with you; and you shall come into the ark—you and your [three] sons and your wife, and your sons’ wives with you. And of every living thing [found on land], you shall bring two of every kind into the ark, to keep them alive with you; they shall be male and female. Of fowls and birds according to their kind, of animals according to their kind, of every crawling thing of the ground according to its kind—two of every kind shall come to you to keep them alive. Also take with you every kind of food that is edible, and you shall collect and store it; and it shall be food for you and for them.” So Noah did this; according to all that God commanded him, that is what he did.
