After having invoked God’s blessing on his rule by offering sacrifices, he obtained the support of his father’s most respected counselor, Ahithophel. Many now swung to Absalom’s side.​—2Sa 15:7-12.

Then, acting on Ahithophel’s counsel, Absalom publicly had relations with his father’s concubines as proof of the complete break between himself and David and of his unrelenting determination to maintain control of the throne. (2Sa 16:15-23)

Ahithophel now urged Absalom to charge him with authority to lead a force against David that very night so as to administer the deathblow before David’s forces could get organized. Pleased, Absalom still thought it wise to hear Hushai’s opinion. Realizing David’s need for time, Hushai painted a vivid picture, possibly designed to play on any lack of genuine courage in Absalom (who, till now, had displayed more arrogance and craftiness than manly valor), as well as to appeal to Absalom’s vanity. Hushai recommended the taking of time first to build up an overwhelming force of men to be then commanded by Absalom himself. By Jehovah’s direction, Hushai’s counsel was accepted. Ahithophel, evidently realizing that Absalom’s revolt would fail, committed suicide.​—2Sa 17:1-14, 23.
