2 Samuel 16:15-22

15Then Absalom and all the people, the men of Israel, entered Jerusalem, and Ahithophel with him.

16Now it happened when Hushai the Archite, David’s friend, came to Absalom, Hushai said to him, “Long live the king! Long live the king!”

17Absalom said to Hushai, “Is this your loyalty to your friend? Why did you not go with your friend?”

18Hushai said to Absalom, “No! For whomever the Lord and this people and all the men of Israel have chosen [as king], I will be his, and I will remain with him.

19Besides, whom should I serve? Should I not serve in the presence of David’s son? As I have served in your father’s presence, so I shall serve in your presence.”

20Then Absalom said to Ahithophel, “Give me your advice. What should we do?”

21Ahithophel said to Absalom, “Go in to your father’s concubines, whom he has left behind to take care of the house; then all Israel will hear that you have made yourself odious to your father. Then the hands of all who are with you will be strengthened [by your boldness and audacity].”

22So they pitched a tent for Absalom on the roof [of the king’s palace], and Absalom went in to his father’s concubines in the sight of all Israel.
