Genesis 9:15-17

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.” And God said to Noah, “This [rainbow] is the sign of the covenant (solemn pledge, binding agreement) which I have established between Me and all living things on the earth.”
