2 Samuel 15:29-35

29Therefore Zadok and Abiathar carried the ark of God back to Jerusalem. And they remained there.

30So David went up by the Ascent of the Mount of Olives, and wept as he went up; and he had his head covered and went barefoot. And all the people who were with him covered their heads and went up, weeping as they went up.

31Then someone told David, saying, “Ahithophel is among the conspirators with Absalom.” And David said, “O Lord, I pray, turn the counsel of Ahithophel into foolishness!”

32Now it happened when David had come to the top of the mountain, where he worshiped God—there was Hushai the Archite coming to meet him with his robe torn and dust on his head.

33David said to him, “If you go on with me, then you will become a burden to me.

34But if you return to the city, and say to Absalom, ‘I will be your servant, O king; as I was your father’s servant previously, so I will now also be your servant,’ then you may defeat the counsel of Ahithophel for me.

35And do you not have Zadok and Abiathar the priests with you there? Therefore it will be that whatever you hear from the king’s house, you shall tell to Zadok and Abiathar the priests.
