Genesis 6:13-15 Complete Jewish Bible (CJB)
13 God said to Noach, “The end of all living beings has come before me, for because of them the earth is filled with violence. I will destroy them along with the earth. 14 Make yourself an ark of gofer-wood; you are to make the ark with rooms and cover it with pitch both outside and inside. 15 Here is how you are to build it: the length of the ark is to be 450 feet, its width seventy-five feet and its height forty-five feet.
