Genesis 9:15-17

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.”
