¹⁴ So make yourself an ark of cypress^[a] wood;^(A) make rooms in it and coat it with pitch^(B) inside and out. ¹⁵ This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high.^{[b] 16} Make a roof for it, leaving below the roof an opening one cubit^[c] high all around.^[d] Put a door in the side of the ark and make lower, middle and upper decks.
