Genesis 3
14 The LORD God said to the serpent, “Because you have done this, cursed are you above all cattle, and above all wild animals; upon your belly you shall go, and dust you shall eat all the days of your life.
15 I will put enmity between you and the woman, and between your seed and her seed; he shall bruise your head, and you shall bruise his heel.”
