Genesis 9:12-16

God said: This is the sign of the covenant that I am making between me and you and every living creature with you for all ages to come: I set my bow in the clouds to serve as a sign of the covenant between me and the earth. When I bring clouds over the earth, and the bow appears in the clouds, I will remember my covenant between me and you and every living creature—every mortal being—so that the waters will never again become a flood to destroy every mortal being. When the bow appears in the clouds, I will see it and remember the everlasting covenant between God and every living creature—every mortal being that is on earth.
