God Gave Noah The Rainbow Sign: No More Water, But The Fire Next Time

"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 - that the waters shall never again be a flood to destroy every living creature- every mortal being that is on earth.

God told Noah: this is the sign of the covenant  I have established between me and every mortal being that is on earth."  Genesis 9:12-17
