2 Samuel 15:32-34

32And it came to pass, when David had come to the summit, where he worshipped 1God, that behold, Hushai the Archite came to meet him with his coat rent, and earth upon his head.

33And David said to him, If thou passest on with me, thou wilt be a burden to me;

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