'Enmity' in the Bible

And I will put enmity between thee and the woman, and between thy seed and her seed; he shall crush thy head, and thou shalt crush his heel.

or from enmity smite him with his hand, so that he die, he that smote him shall certainly be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meeteth him. --

But if he have thrust at him suddenly without enmity, or have cast upon him anything unintentionally,

The days of visitation are come; the days of recompence are come: Israel shall know it: the prophet is a fool, the inspired man is mad, because of the greatness of thine iniquity, and the great enmity.

Is Ephraim a watchman with my God? nay the prophet is a fowler's snare on all his ways, enmity in the house of his God.
