Genesis 6:14-16

14Make for yourself an ark of 1gopher wood; you shall make the ark with compartments, and 2cover it inside and out with pitch.

15This is how you shall make it: the length of the ark shall be 3three hundred cubits, its width fifty cubits, and its height thirty cubits.

16You shall make a 4window for the ark, and finish it to a 5cubit from 6the top; and put the door of the ark on the side; you shall make it with lower, second, and third decks.
