1 Kings 1:35-39

Then you shall come up after him, and he shall come and sit on my throne, and he shall be king in my place; for I have appointed him to be ruler over Israel and Judah.”

Benaiah the son of Jehoiada answered the king and said, “Amen! May the Lord, the God of my lord the king, say the same.

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!” Solomon Anointed King

So Zadok the priest, Nathan the prophet, Benaiah the son of Jehoiada, the Cherethites, and the Pelethites went down and had Solomon ride on King David’s mule, and brought him to Gihon.
