Genesis 6:15-17

New Revised Standard Version Catholic Edition

¹⁵ This is how you are to make it: the length of the ark three hundred cubits, its width fifty cubits, and its height thirty cubits. ¹⁶ Make a roof^[a] for the ark, and finish it to a cubit above; and put the door of the ark in its side; make it with lower, second, and third decks. ¹⁷ For my part, I am going to bring a flood of waters on the earth, to destroy from under heaven all flesh in which is the breath of life; everything that is on the earth shall die.
