Genesis 6:13-15 21st Century King James Version (KJ21)
13 And God said unto Noah, “The end of all flesh has come before Me, for the earth is filled with violence through them; and behold, I will destroy them with the earth.
14 Make thee an ark of gopherwood; rooms shalt thou make in the ark, and shalt cover it within and without with pitch.
15 And this is the fashion which thou shalt make it of: the length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.
Genesis 6:13-15 New International Version (NIV)
13 So God said to Noah, “I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth. 14 So make yourself an ark of cypress[a] wood; make rooms in it and coat it with pitch inside and out. 15 This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high.[b]
