2 Samuel 16:15-22

15Now Absalom and all the Israelites came to Jerusalem. Ahithophel was also with him.

16When David’s friend Hushai the Archite came to Absalom, Hushai said to Absalom, “Long live the king! Long live the king!”

17“Is this your loyalty to your friend?” Absalom asked Hushai. “Why didn’t you go with your friend?”

18“Not at all,” Hushai answered Absalom. “I am on the side of the one that the Lord, this people, and all the men of Israel have chosen. I will stay with him.

19Furthermore, whom will I serve if not his son? As I served in your father’s presence, I will also serve in yours.”

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

21Ahithophel replied to Absalom, “Sleep with your father’s concubines whom he left to take care of the palace. When all Israel hears that you have become repulsive to your father, everyone with you will be encouraged.”

22So they pitched a tent for Absalom on the roof, and he slept with his father’s concubines in the sight of all Israel.
