1 Kings 1:33-35

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! ’

35You are to come up after him, and he is to come in and sit on my throne. He is the one who is to become king in my place; he is the one I have commanded to be ruler over Israel and Judah.”
