'Blew a Trumpet' in the Bible

So Joab blew the trumpet; and all the people halted and no longer pursued Israel, nor did they fight anymore.

There happened to be there a worthless and wicked man named Sheba the son of Bichri, a Benjamite. He blew a trumpet [to call Israel to revolt] and said,“We have no portion in DavidAnd no inheritance in the son of Jesse,Every man to his tents, O Israel!”
