Genesis 6:13-15 International Standard Version (ISV)
13 So God announced to Noah, “I’ve decided to destroy every living thing on earth,[a] because it has become filled with violence due to them. Look! I’m about to annihilate them, along with the earth. 14 So make yourself an ark out of cedar,[b] constructing compartments in it, and cover it inside and out with tar. 15 Make the ark like this: 300 cubits[c] long, 50 cubits[d] wide, and 30 cubits[e] high.
