1 Kings 1:33-35

And the king said to them, “Take with you the servants of your lord and have Solomon my son ride on my own mule, and bring him down to Gihon. And let Zadok the priest and Nathan the prophet there anoint him king over Israel. Then blow the trumpet and say, ‘Long live King Solomon!’ You shall then come up after him, and he shall come and sit on my throne, for he shall be king in my place. And I have appointed him to be ruler over Israel and over Judah.”
