That is the Promise of Genesis 3:15

The offspring of Satan are all who oppose God’s plan of redemption – Cain, Ham, the Canaanites, and the pharaoh in Egypt who will end up enslaving God’s people for over four hundred years.  God orchestrates a plan to fix creation by working through the womb of women.  Ultimately, a descendent of Eve will “bruise” (or “crush”) the head of Satan.  That’s the promise of Genesis 3:15.  And that’s why this verse is the first of many so-called messianic promises of the Bible.
