2 Samuel 15:29-35

29Zadok therefore and Abiathar carried the ark of God again to Jerusalem: and they tarried there. 30And David went up by the ascent of mount Olivet, and wept as he went, and had his head covered, and he went barefoot: and all the people that were with him covered every man his head, and they went up, weeping as they went.1

31And onetold David, saying, Ahithophelis among the conspirators with Absalom. And David said, O LORD, I pray thee, turn the counsel of Ahithophel into foolishness. 32And it came to pass, that when David had come to the top of the mount, where he worshipped God, behold, Hushai the Archite came to meet him with his coat torn, and earth upon his head: 33To whom David said, If thou shalt pass on with me, then thou shalt be a burden to me: 34But if thou shalt return to the city, and say to Absalom, I will be thy servant, O king; as I have been thy father’s servant to this time, so will I now also be thy servant: then mayest thou for me defeat the counsel of Ahithophel. 35And hast thou not there with thee Zadok and Abiathar the priests? therefore it shall be, that whatever thing thou shalt hear out of the king’s house, thou shalt tell it to Zadok and Abiathar the priests.
