'Horn' in the Bible

He hath cut off in fierce anger all the horn of Israel; He hath drawn back his right hand from before the enemy: And he hath burned up Jacob like a flaming fire, which devoureth round about.

Jehovah hath done that which he purposed; he hath fulfilled his word that he commanded in the days of old; He hath thrown down, and hath not pitied: And he hath caused the enemy to rejoice over thee; he hath exalted the horn of thine adversaries.
