2 Samuel 15:32

30And David went up by the ascent of mount Olivet, and wept as he went up, and had his head covered, and he went barefoot: and all the people that was with him covered every man his head, and they went up, weeping as they went up.

31And one told David, saying, Ahithophel is 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 was come to the top of the mount, where he worshipped God, behold, Hushai the Archite came to meet him with his coat rent, and earth upon his head:

33Unto whom David said, If thou passest on with me, then thou shalt be a burden unto me:

34But if thou return to the city, and say unto Absalom, I will be thy servant, O king; as I have been thy father’s servant hitherto, so will I now also be thy servant: then mayest thou for me defeat the counsel of Ahithophel.
