I Kings 1:5-8

Then Adonijah the son of Haggith exalted himself, saying, “I will be king”; and he prepared for himself chariots and horsemen, and fifty men to run before him. (And his father had not rebuked him at any time by saying, “Why have you done so?” He was also very good-looking. His mother had borne him after Absalom.) Then he conferred with Joab the son of Zeruiah and with Abiathar the priest, and they followed and helped Adonijah. But Zadok the priest, Benaiah the son of Jehoiada, Nathan the prophet, Shimei, Rei, and the mighty men who belonged to David were not with Adonijah.
