“I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.”

And the LORD God made for Adam and for his wife garments of skins and clothed them. (Cf. Isaiah 61:10: I will greatly rejoice in the LORD; my soul shall exalt in my God, for he has clothed me with the garments of salvation; he has covered me with the robe of righteousness, as a bridegroom decks himself like a priest with a beautiful headdress, and as a bride adorns herself with her jewels.)

– Genesis 3:15, 21

Verses 22-24: God graciously prevents Adam and Eve from eating from the tree of life, thus remaining in their cursed state forever so He banished them from the garden of Eden. From that point on, the way forward was to the Cross.
