2 Samuel 16:20-17:4

20Absalom said to Ahithophel, “Give us your advice. What should we do?” 21Ahithophel answered, “Sleep with your father’s concubines whom he left to take care of the palace. Then all Israel will hear that you have made yourself obnoxious to your father, and the hands of everyone with you will be more resolute.”

22So they pitched a tent for Absalom on the roof, and he slept with his father’s concubines in the sight of all Israel. 23Now in those days the advice Ahithophel gave was like that of one who inquires of God. That was how both David and Absalom regarded all of Ahithophel’s advice.

1Ahithophel said to Absalom, “I would Or Let me choose twelve thousand men and set out tonight in pursuit of David. 2I would attack him while he is weary and weak. I would strike him with terror, and then all the people with him will flee. I would strike down only the king 3and bring all the people back to you. The death of the man you seek will mean the return of all; all the people will be unharmed.”

4This plan seemed good to Absalom and to all the elders of Israel.
