Genesis 9:14-17

14Whenever I form clouds over the earth, a rainbow will appear in the clouds.

15Then I will remember my promise to you and every living animal. Never again will water become a flood to destroy all life.

16Whenever the rainbow appears in the clouds, I will see it and remember my everlasting promise to every living animal on earth.”

17So God said to Noah, “This is the sign of the promise I am making to all life on earth.”
