Genesis 9:11-17

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. Whenever I bring clouds over the earth, and the rainbow appears in the clouds, I will remember my covenant with you and with every living thing upon the earth. Never again will the waters become a flood to destroy life from the earth. When the rainbow is in the clouds, I will see it and remember the everlasting covenant I made with you and every living thing of every kind upon the earth.” So God said to Noah, “The rainbow is my signature in the sky, my seal of love to confirm that I have kept my covenant between me and every living thing on earth.”
