Genesis 6:14-16

Make thee an Arke of pine trees: thou shalt make cabines in the Arke, and shalt pitch it within and without with pitch.

And thus shalt thou make it: The length of the Arke shalbe three hundreth cubites, the breadth of it fiftie cubites, and the height of it thirtie cubites.

A windowe shalt thou make in the Arke, and in a cubite shalt thou finish it aboue, and the doore of the Arke shalt thou set in the side thereof: thou shalt make it with the lowe, seconde and third roume.
