The first prophecy in the Bible regarding the coming of Jesus was given after sin was introduced into the world in the Garden of Eden. In His curse to the serpent, God said, “And I will put enmity between you and the woman, and between your seed and her seed; He shall bruise you on the head, and you shall bruise him on the heel” (Genesis 3:15).
God was describing an event in which the seed of woman – Jesus – would be injured (His “heel” would be bruised) and Satan would be defeated (his “head” would be bruised or crushed). Remember that Satan came in the form of a serpent. We can imagine what would happen if someone were to kill a snake – one’s foot might be injured in crushing the head of the snake, but the snake would be killed. This prophecy was looking forward to the death of Christ.
