1 Kings 1:32-37

Then King David said, “Call Zadok the priest, Nathan the prophet, and Benaiah the son of Jehoiada to me.” And they came before the king. The king told them, “Take the servants of your lord with you and have Solomon my son ride on my own mule, and bring him down to [the spring at] Gihon [in the Kidron Valley]. Let Zadok the priest and Nathan the prophet anoint him there as king over Israel. Then blow the trumpet and say, ‘Long live King Solomon!’ Then you shall come up [to Jerusalem] after him, and he shall come and sit on my throne and he shall reign as king in my place; for I have appointed him to be ruler over Israel and Judah.” Benaiah [the overseer of the king’s bodyguards], the son of Jehoiada answered the king and said, “Amen! (So be it!) May the LORD, the God of my lord the king, say so too. Just as the LORD has been with my lord the king, so may He be with Solomon, and make his throne greater than the throne of my lord King David!”
