Genesis 6:10-15

And Noah begat three sons, Shem, Ham, and Japheth. And the earth was corrupt before God, and the earth was filled with violence. And God saw the earth, and, behold, it was corrupt; for all flesh had corrupted their way upon the earth. And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth. Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch. And this is how thou shalt make it: the length of the ark three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.
