Genesis 3:14-15

14So the LORD God said to the serpent, “Because you have done this, “Cursed are you above all livestock and all wild animals! You will crawl on your belly and you will eat dust all the days of your life.

15And I will put enmity between you and the woman, and between your offspring Or seed and hers; he will crush Or strike your head, and you will strike his heel.”
