2 Samuel 15:29-37

15:29 So Zadok and Abiathar took the ark of God back to Jerusalem and remained there.

15:30 As David was going up the Mount of Olives, he was weeping as he went; his head was covered and his feet were bare. All the people who were with him also had their heads covered and were weeping as they went up. 15:31 Now David had been told, “Ahithophel has sided with the conspirators who are with Absalom. So David prayed, “Make the advice of Ahithophel foolish, O Lord!”

15:32 When David reached the summit, where he used to worship God, Hushai the Arkite met him with his clothes torn and dirt on his head. 15:33 David said to him, “If you leave with me you will be a burden to me. 15:34 But you will be able to counter the advice of Ahithophel if you go back to the city and say to Absalom, ‘I will be your servant, O king! Previously I was your father’s servant, and now I will be your servant.’ 15:35 Zadok and Abiathar the priests will be there with you. Everything you hear in the king’s palace you must tell Zadok and Abiathar the priests. 15:36 Furthermore, their two sons are there with them, Zadok’s son Ahimaaz and Abiathar’s son Jonathan. You must send them to me with any information you hear.”

15:37 So David’s friend Hushai arrived in the city, just as Absalom was entering Jerusalem.
