1 Kings 1:32-35

Then King David said, “Call to me Zadok the priest, Nathan the prophet, and Benaiah the son of Jehoiada.” And they came into the king’s presence. The king said to them, “Take with you the servants of your lord, and have my son Solomon ride on my own mule, and bring him down to Gihon. Let Zadok the priest and Nathan the prophet anoint him there as king over Israel, and blow the trumpet and say, ‘Long live King Solomon!’ Then you shall come up after him, and he shall come and sit on my throne and be king in my place; for I have appointed him to be ruler over Israel and Judah.”
