Genesis 6:14-18

Make for yourself an ark of gopher wood; you shall make the ark with compartments, and cover it inside and out with pitch.

This is how you shall make it: the length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits.

You shall make a window for the ark, and finish it to a cubit from the top; and put the door of the ark on the side; you shall make it with lower, second, and third decks.

Now behold, I Myself am bringing the flood of water upon the earth, to destroy all flesh in which there is the breath of life, from under heaven; everything that is on the earth shall perish.

But I will establish My covenant with you; and you shall enter the ark—you, your sons, your wife, and your sons’ wives with you.
