I Kings 1:32-34

And King David said, “Call to me Zadok the priest, Nathan the prophet, and Benaiah the son of Jehoiada.” So they came before the king. The king also said to them, “Take with you the servants of your lord, and have Solomon my son ride on my own mule, and take him down to Gihon. There let Zadok the priest and Nathan the prophet anoint him king over Israel; and blow the horn, and say, ‘Long live King Solomon!’
