2 Samuel 15:32-37

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.

35Won’t you have with you Zadok and Abiathar the kohanim there? So whatever you hear from the royal palace, you should report it to Zadok and Abiathar the kohanim.

36See, they have their two sons with them there, Zadok’s son Ahimaaz, and Abiathar’s son Jonathan—by them you can send to me everything you hear.”

37So David’s friend Hushai reached the city just as Absalom was entering Jerusalem.
