'Horn' in the Bible

In his burning wrath every horn of Israel has been cut off; his right hand has been turned back before the attacker: he has put a fire in Jacob, causing destruction round about.

The Lord has done that which was his purpose; he has put into force the orders which he gave in the days which are past; pulling down without pity, he has made your hater glad over you, lifting up the horn of those who were against you.
