1 Kings 1:32-34

32King David said, ‘Send to me Zadok the priest, Nathan the prophet and Jehoiada's son Benaiah.’ So they came to the king.

33The king said to them, ‘Take my officers with you and put my son Solomon on my own mule. Then lead him down to Gihon, as he rides on the mule.

34There, Zadok the priest and Nathan the prophet can anoint him to be king over Israel. Make a loud noise with a trumpet and shout, “May King Solomon live for a long time!”
