'Horn' in the Bible

He has cut off in fierce anger all the horn of Israel; He has drawn back his right hand from before the enemy: He has burned up Jacob like a flaming fire, which devours all around.

Yahweh has done that which he purposed; he has fulfilled his word that he commanded in the days of old; He has thrown down, and has not pitied: He has caused the enemy to rejoice over you; he has exalted the horn of your adversaries.
