'Trumpet' in the Bible

Let Zadok the priest and Nathan the prophet anoint him there as king over Israel. Then blow the trumpet and say, ‘Long live King Solomon!’

Zadok the priest took a horn of [olive] oil from the [sacred] tent and anointed Solomon. They blew the trumpet, and all the people said, “Long live King Solomon!”

Now Adonijah and all the guests who were with him heard it as they finished eating. When Joab heard the trumpet sound, he said, “Why is the city in such an uproar?”
