'Enmity' in the Bible

The days of visitation are come, the days of recompense are come; Israel shall know it: the prophet is a fool, the man that hath the spirit is mad, for the abundance of thine iniquity, and because the enmity is great.

Ephraim was a watchman with my God: as for the prophet, a fowler's snare is in all his ways, and enmity in the house of his God.
