1 Kings 1:5-7
5 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.
6 And his father had not displeased him at any time in saying, Why hast thou done so? and he also was a very goodly man; and his mother bare him after Absalom.
7 And he conferred with Joab the son of Zeruiah, and with Abiathar the priest: and they following Adonijah helped him.
