'Trumpet' in the Bible

Let Zadok the priest and Nathan the prophet anoint him there king over Israel. Blow the trumpet, and say, 'Long live king Solomon!'

Zadok the priest took the horn of oil out of the Tent, and anointed Solomon. They blew the trumpet; and all the people said, "Long live king Solomon!"

Adonijah and all the guests who were with him heard it as they had made an end of eating. When Joab heard the sound of the trumpet, he said, "Why is this noise of the city being in an uproar?"
