Genesis 6:16 in the King James Version
A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.
Context
15 This is how you shall make it. The length of the ship shall be three hundred cubits, its width fifty cubits, and its height thirty cubits.
16 You shall make a roof in the ship, and you shall finish it to a cubit upward. You shall set the door of the ship in its side. You shall make it with lower, second, and third levels.
17 I, even I, will bring the flood of waters on this earth, to destroy all flesh having the breath of life from under the sky. Everything that is on the earth will die.
