Genesis 6:15-17

Lexham English Bible

¹⁵ And this is how you must make it: the length of the ark, three hundred cubits; its width fifty cubits; its height, thirty cubits. ¹⁶ You must make a roof for the ark, and finish it to a cubit above.^[a] And as for the door of the ark, you must put it in its side. You must make it with a lower, second, and a third deck.

¹⁷ And I, behold, I am about to bring the flood waters over the earth to destroy all flesh in which is the breath of life from under the heaven;^[b] everything that is on the earth shall perish.
