1 Kings 1:44-45

44He sent these people to put Solomon onto the king's mule: Zadok the priest, Nathan the prophet, Jehoiada's son Benaiah, and the king's personal guards. They took Solomon to Gihon.

45Then Zadok the priest and Nathan the prophet anointed Solomon at Gihon to become king. They have taken him from there into the city with happy shouts. People are shouting everywhere. That is the noise that you can hear.
