1 Kings 1:5, 32-37

Adonijah was the son of King David and Haggith, and he was very proud. “I will be the king,” he said. So he got chariots and horses for himself and fifty men for his personal bodyguard.

Then King David said, “Tell Zadok the priest, Nathan the prophet, and Benaiah son of Jehoiada to come in.” When they came before the king, he said to them, “Take my servants with you and put my son Solomon on my own mule. Take him down to the spring called Gihon. There Zadok the priest and Nathan the prophet should pour olive oil on him and make him king over Israel. Blow the trumpet and shout, ‘Long live King Solomon!’ Then come back up here with him. He will sit on my throne and rule in my place, because he is the one I have chosen to be the ruler over Israel and Judah.” Benaiah son of Jehoiada answered the king, “Amen! This is what the LORD, the God of my master, has declared! The LORD has always helped you, our king. May he also help Solomon and make King Solomon’s throne an even greater throne than yours.”
