Genesis 6:13-15 New American Bible (Revised Edition) (NABRE)
13 God said to Noah: I see that the end of all mortals has come, for the earth is full of lawlessness because of them. So I am going to destroy them with the earth.
Preparation for the Flood. 14 Make yourself an ark of gopherwood,[a] equip the ark with various compartments, and cover it inside and out with pitch. 15 This is how you shall build it: the length of the ark will be three hundred cubits, its width fifty cubits, and its height thirty cubits.[b]
