Genesis 9:13-16

I have placed my rainbow among the clouds, and it will be a sign of my loving covenant between me and the earth. Whenever I bring clouds over the earth, and the rainbow appears in the clouds, 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.”
