2 Samuel 15:32-37

32When David arrived at the summit, where people used to worship God, Hushai the Arkite was there to meet him, his robe torn and dust on his head. 33David said to him, “If you go with me, you will be a burden to me. 34But if you return to the city and say to Absalom, ‘Your Majesty, I will be your servant; I was your father’s servant in the past, but now I will be your servant,’ then you can help me by frustrating Ahithophel’s advice. 35Won’t the priests Zadok and Abiathar be there with you? Tell them anything you hear in the king’s palace.

36Their two sons, Ahimaaz son of Zadok and Jonathan son of Abiathar, are there with them. Send them to me with anything you hear.” 37So Hushai, David’s confidant, arrived at Jerusalem as Absalom was entering the city.
