'Horn' in the Bible

Then Joab blew the ram’s horn, and all the troops stopped; they no longer pursued Israel or continued to fight.

He and the whole house of Israel were bringing up the ark of the Lord with shouts and the sound of the ram’s horn.

Then Absalom sent messengers throughout the tribes of Israel with this message: “When you hear the sound of the ram’s horn, you are to say, ‘Absalom has become king in Hebron!’”

Afterward, Joab blew the ram’s horn, and the troops broke off their pursuit of Israel because Joab restrained them.

Now a wicked man, a Benjaminite named Sheba son of Bichri, happened to be there. He blew the ram’s horn and shouted:We have no portion in David,no inheritance in Jesse’s son.Each man to his tent, Israel!

The woman went to all the people with her wise counsel, and they cut off the head of Sheba son of Bichri and threw it to Joab. So he blew the ram’s horn, and they dispersed from the city, each to his own tent. Joab returned to the king in Jerusalem.

The God of my rock; in him will I trust: he is my shield, and the horn of my salvation, my high tower, and my refuge, my saviour; thou savest me from violence.
