2 Samuel 15:32-36
32-36As David approached the top of the hill where God was worshiped, Hushai the Arkite, clothes ripped to shreds and dirt on his head, was there waiting for him. David said, "If you come with me, you'll be just one more piece of luggage. Go back to the city and say to Absalom, 'I'm ready to be your servant, O King; I used to be your father's servant, now I'm your servant.' Do that and you'll be able to confuse Ahithophel's counsel for me. The priests Zadok and Abiathar are already there; whatever information you pick up in the palace, tell them. Their two sons—Zadok's son Ahimaaz and Abiathar's son Jonathan—are there with them—anything you pick up can be sent to me by them."
37Hushai, David's friend, arrived at the same time Absalom was entering Jerusalem.
