1 Kings 1:32-34

32King David then said, “Call in the priest Zadok, the prophet Nathan, and Benaiah son of Jehoiada for me.” So they came into the king’s presence.

33The king said to them, “Take my servants with you, have my son Solomon ride on my own mule, and take him down to Gihon.

34There, the priest Zadok and the prophet Nathan are to anoint him as king over Israel. You are to blow the ram’s horn and say, ‘Long live King Solomon! ’
