II Samuel 16:15–23

But Absalom and all his people came into Jerusalem, and Achitophel was with him. 16And when Chusai the Arachite, David's friend, was come to Absalom, he said to him: God save thee, O king, God save thee, O king. 17And Absalom said to him, Is this thy kindness to thy friend? Why wentest thou not with thy friend? 18And Chusai answered Absalom: Nay: for I will be his, whom the Lord hath chosen, and all this people, and all Israel, and with him will I abide. 19Besides this, whom shall I serve? is it not the king's son? as I have served thy father, so will I serve thee also. 20And Absalom said to Achitophel: Consult what we are to do. 21And Achitophel said to Absalom: Go in to the concubines of thy father, whom he hath left to keep the house: that when all Israel shall hear that thou hast disgraced thy father, their hands may be strengthened with thee. 22So they spread a tent for Absalom on the top of the house, and he went in to his father's concubines before all Israel. 23Now the counsel of Achitophel, which he gave in those days, was as if a man should consult God: so was all the counsel of Achitophel, both when he was with David, and when he was with Absalom.
