Genesis 9:13-16

I set My rainbow in the clouds, and it shall be a sign of a covenant between Me and the earth. It shall come about, when I bring clouds over the earth, that the rainbow shall be seen in the clouds, and I will [compassionately] remember My covenant, which is between Me and you and every living creature of all flesh; and never again will the water become a flood to destroy all flesh. When the rainbow is in the clouds and I look at it, I will [solemnly] remember the everlasting covenant between God and every living creature of all flesh that is on the earth.”
