Genesis 6:16-18

16 Make a roof for the ark, and finish it to a cubit above, and set the door of the ark in its side. Make it with lower, second, and third decks.

17 For behold, I will bring a flood of waters upon the earth to destroy all flesh in which is the breath of life under heaven. Everything that is on the earth shall die.

18 But I will establish my covenant with you, and you shall come into the ark, you, your sons, your wife, and your sons' wives with you.
