'Trumpet' in the Bible

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

Then Zadok the priest took the horn of oil from the tent, and he anointed Solomon. They blew on the trumpet, and all the people said, "Long live King Solomon!"

And Adonijah and all the invited guests who were with him heard [it]. Now they were finished eating when Joab heard the sound of the trumpet and said, "{Why is there such a noise in the city?}"
