Genesis 9:11-13

I will maintain my loving covenant with you. I will never again completely destroy life on earth by means of a flood. Yes, never again will a flood destroy the whole earth!” “Here is the sign for you and future generations that my loving covenant will endure between me and you and every animal that came with you out of the ark: I have placed my rainbow among the clouds, and it will be a sign of my loving covenant between me and the earth.
