'Hostility' in the Bible

I will put hostility between you and the woman,and between your seed and her seed.He will strike your head,and you will strike his heel.

And he shall be a wild donkey of a man, his hand [will be] against everyone, and the hand of everyone [will be] against him, and he will live {in hostility with all his brothers}."

Then they dug another well and quarreled over that one also, so he named it Hostility.
