"And God said, “This is the sign of the covenant which I make between me and you and every living creature that is with you, for all future generations:
I set my rainbow in the cloud, and it shall be a sign of the covenant between me and the earth.
When I bring clouds over the earth and the rainbow is seen in the clouds, I will remember my covenant which is between me and you and every living creature of all flesh;
and the waters shall never again become a flood to destroy all flesh."
- Genesis 9:12-15
