'Trumpet' in the Bible

So Joab sounded his battle trumpet, his entire army stopped pursuing Israel any longer, and they quit fighting.

So David and the entire assembly of Israel brought up the ark of the LORD with shouting and trumpet blasts.

But Absalom sent agents throughout all of the tribes of Israel, telling them, "When you hear the sound of the battle trumpet, you're to announce that Absalom is king in Hebron."

At this, Joab sounded his battle trumpet and his troops stopped pursuing the other Israelis.

Right about then, Bichri's son Sheba, an ungodly man from the tribe of Benjamin, sounded a battle trumpet and announced: We've never been a part of David! We'll never gain anything from Jesse's son! It's every man to his tent, Israel!

So the woman replied, "Watch this! His head will be thrown to you over the city wall." Then the woman wisely went back to her people. They cut off the head of Bichri's son Sheba and threw it out to Joab, so Joab sounded his battle trumpet and they withdrew from the city. Everybody went back home and Joab returned to the king at Jerusalem.
