13 So God said to Noah, "I have decided to destroy everyone, because all over the earth people are acting violently toward each other. So I am about to get rid of them as well as everything else on the earth. 14 I want you to make for yourself a large boat from cypress wood. Make rooms inside it. Cover the outside and the inside with tar to make it ◄waterproof/so that water cannot get in and sink the boat►. 15 This is the size you must make it: It shall be ◄150 yards/135 meters► long, ◄25 yards/22.5 meters► wide, and ◄15 yards/13.5 meters► high. 16 Make a roof for the boat. Leave a space of about ◄18 in./.5 meter► between the sides and the roof to let air and light enter (OR, the middle of the roof should be 18 inches higher than the sides). Build the boat with three decks inside, and put a door in one side.
