1 Kings 1:5-8

Now Adonijah, whose mother was Haggith, put himself forward and said, “I will be king.” So he got chariots and horses ready, with fifty men to run ahead of him. (His father had never rebuked him by asking, “Why do you behave as you do?” He was also very handsome and was born next after Absalom.) Adonijah conferred with Joab son of Zeruiah and with Abiathar the priest, and they gave him their support. But Zadok the priest, Benaiah son of Jehoiada, Nathan the prophet, Shimei and Rei and David’s special guard did not join Adonijah.
