1 Kings 1:5-8

Then Adonijah the son of Haggith exalted himself, saying, I will be king: and he prepared him chariots and horsemen, and fifty men to run before him. And his father had not displeased him at any time in saying, Why hast thou done so? and he was also a very goodly man; and he was born after Absalom. And he conferred with Joab the son of Zeruiah, and with Abiathar the priest: and they following Adonijah helped him. But Zadok the priest, and Benaiah the son of Jehoiada, and Nathan the prophet, and Shimei, and Rei, and the mighty men that belonged to David, were not with Adonijah.
