2 Samuel 15:32-37

32 When David came to the summit, where God was worshiped, Hushai the Archite came to meet him with his coat torn and earth on his head.
33 David said to him, "If you go on with me, you will be a burden to me.
34 But if you return to the city and say to Absalom, "I will be your servant, O king; as I have been your father's servant in time past, so now I will be your servant,' then you will defeat for me the counsel of Ahithophel.
35 The priests Zadok and Abiathar will be with you there. So whatever you hear from the king's house, tell it to the priests Zadok and Abiathar.
36 Their two sons are with them there, Zadok's son Ahimaaz and Abiathar's son Jonathan; and by them you shall report to me everything you hear."
37 So Hushai, David's friend, came into the city, just as Absalom was entering Jerusalem.
