Genesis 6:15-16; Genesis 7:20
This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high.
Make a roof for it, leaving below the roof an opening one cubit high all around. Put a door in the side of the ark and make lower, middle and upper decks.
The waters rose and covered the mountains to a depth of more than fifteen cubits.
