1 Kings 1:38-39

38So Zadok the priest, Nathan the prophet, Benaiah son of Jehoiada, the Kerethites and the Pelethites went down and had Solomon mount King David’s mule, and they escorted him to Gihon. 39Zadok the priest took the horn of oil from the sacred tent and anointed Solomon. Then they sounded the trumpet and all the people shouted, “Long live King Solomon!”
