And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.
All Commentaries on Genesis 9:16 Go To Genesis 9
Gregory the Theologian
AD 390
Who “binds up the water in the clouds”? The miracle of it—that he sets something whose nature is to flow, on clouds, that he fixes it there by his word! Yet he pours out some of it on the face of the whole earth, sprinkling it to all alike in due season. He does not unleash the entire stock of water—the cleansing of Noah’s era was enough, and God most true does not forget his own covenant.
