“Build a large boat  from cypress wood and waterproof it with tar, inside and out.  Then construct decks and stalls throughout its interior. ¹⁵ Make the boat 450 feet long, 75 feet wide, and 45 feet high. ¹⁶ Leave an 18-inch opening below the roof all the way around the boat.  Put the door on the side, and build three decks inside the boat—lower, middle, and upper."

(Genesis 6:14-16 -- NLT)
