1 Kings 1:38-40
38-40Then Zadok the priest, Nathan the prophet, Benaiah son of Jehoiada, and the king's personal bodyguard (the Kerethites and Pelethites) went down, mounted Solomon on King David's mule, and paraded with him to Gihon. Zadok the priest brought a flask of oil from the sanctuary and anointed Solomon. They blew the ram's horn trumpet and everyone shouted, "Long live King Solomon!" Everyone joined the fanfare, the band playing and the people singing, the very earth reverberating to the sound.
41Adonijah and his retinue of guests were just finishing their "coronation" feast when they heard it. When Joab heard the blast of the ram's horn trumpet he said, "What's going on here? What's all this uproar?"
