New Defender's Study Bible Notes
8:21 not again curse. The promise of God, given in response to Noah’s sacrificial prayer of thanksgiving and intercession, is tremendous in scope. He would never again “curse the ground” with a worldwide curse as He had done following Adam’s sin. The Edenic curse is still in effect, of course, but there would be no other. Noah had, indeed, brought “comfort” to the world concerning “the ground which the LORD had cursed” (Genesis 5:29).
8:21 every living thing. Neither would God ever again bring a worldwide cataclysm to the earth as He had with the Flood.
