Genesis 6:11-15 NIV

[11] Now the earth was corrupt in God’s sight and was full of violence. [12] God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. [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 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.
