'Trumpet' in the Bible

and let Zadok the priest and Nathan the prophet anoint him there king over Israel; and blow ye the trumpet, and say, Long live king Solomon.

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

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