Genesis 3:14-15

14The Lord God said to the serpent, “Because you have done this, You are cursed more than all the cattle, And more than any animal of the field; On your belly you shall go, And dust you shall eat All the days of your life.

15And I will put enmity (open hostility) Between you and the woman, And between your seed (offspring) and her Seed; He shall [fatally] bruise your head, And you shall [only] bruise His heel.”
