2 Samuel 15:32-34

32Then David went on until he reached the summit—where God was worshiped—and behold, Hushai the Archite met him with his coat rent and dust on his head.

33David said to him, “If you pass on with me then 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—I was your father’s servant from then, but now I will be your servant,’ then you can thwart Ahithophel’s counsel for me.
