Genesis 6:16-18

Amplified Bible

¹⁶ You shall make a ^[a]window [for light and ventilation] for the ark, and finish it to at least a cubit (eighteen inches) from the top—and set the [entry] door of the ark in its side; and you shall make it with lower, second and third decks. ¹⁷ For behold, I, even I, will bring a flood of waters on the earth, to destroy all life under the heavens in which there is the breath and spirit of life; everything that is on the land shall die. ¹⁸ 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.
