Genesis 6:13-15 New English Translation (NET Bible)
13 So God said to Noah, “I have decided that all living creatures must die, for the earth is filled with violence because of them. Now I am about to destroy them and the earth. 14 Make for yourself an ark of cypress wood. Make rooms in the ark, and cover it with pitch inside and out. 15 This is how you should make it: The ark is to be 450 feet long, 75 feet wide, and 45 feet high.
