2 Samuel 15:29-35

29So Zadok and Abiathar brought the ark of God back to Jerusalem, and they stayed there.

30And David went up the ascent of the Mount of Olives, weeping as he went, with his head covered and walking barefoot [in despair]. And all the people who were with him covered their heads and went up, weeping as they went.

31David was told, “Ahithophel [your counselor] is among the conspirators with Absalom.” David said, “O Lord, I pray You, turn Ahithophel’s counsel into foolishness.”

32It happened when David came to the summit [of the Mount of Olives], where he worshiped God, behold, Hushai the Archite came to meet him with his tunic torn and dust on his head [as if in mourning].

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

34But 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 the past, so I will be your servant now;’ then you can thwart (make useless) the advice of Ahithophel for me.

35Are not Zadok and Abiathar the priests with you there? So it shall be that every word you hear from the king’s palace, you shall report it to them.
