19 After all, whom should I serve, if not my master's son? As I served your father, so now I will serve you.”
20 Then Absalom turned to Ahithophel and said, “Now that we are here, what do you advise us to do?”
21 Ahithophel answered, “Go and have intercourse with your father's concubines whom he left behind to take care of the palace. Then everyone in Israel will know that your father regards you as his enemy, and your followers will be greatly encouraged.”
22 So they set up a tent for Absalom on the palace roof, and in the sight of everyone Absalom went in and had intercourse with his father's concubines.
23 Any advice that Ahithophel gave in those days was accepted as though it were the very word of God; both David and Absalom followed it.
