2nd Samuel 15:31

28 Behold, I will stay at the fords of the wilderness, until word comes from you to inform me."

29 Zadok therefore and Abiathar carried the ark of God again to Jerusalem: and they abode there.

30 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 every man his head, and they went up, weeping as they went up.

31 One told David, saying, Ahithophel is among the conspirators with Absalom. David said, Yahweh, please turn the counsel of Ahithophel into foolishness.

32 It happened that when David had come to the top [of the ascent], where God was worshipped, behold, Hushai the Archite came to meet him with his coat torn, and earth on his head.

33 David said to him, If you pass on with me, then you will be a burden to me:

34 but if you return to the city, and tell Absalom, I will be your servant, O king; as I have been your father`s servant in time past, so will I now be your servant; then will you defeat for me the counsel of Ahithophel.
