1 Kings 1:44-46

44And the king has sent with him Zadok the priest, and Nathan the prophet, and Benaiah the son of Jehoiada, and the Cherethites and the Pelethites, and they have caused him to ride upon the king's mule;

45and Zadok the priest and Nathan the prophet have anointed him king at Gihon; and they are come up from thence rejoicing, so that the city is in an uproar. This is the noise which ye have heard.

46And also Solomon is sitting on the throne of the kingdom.
