1 Kings 1:33-35

the king said to them, “Take Solomon and my officials down to Gihon Spring. Solomon is to ride on my own mule. There Zadok the priest and Nathan the prophet are to anoint him king over Israel. Blow the ram’s horn and shout, ‘Long live King Solomon!’ Then escort him back here, and he will sit on my throne. He will succeed me as king, for I have appointed him to be ruler over Israel and Judah.”
