2 Samuel 15:33-37

33David told him, “If you go with me, you will only be a burden to me.

34But if you go back to the city and say to Absalom, ‘Your Majesty, I’ll be your servant. I was your father’s servant in the past, but now I’ll be your servant,’ then you’ll ⌞help me by⌟ undoing Ahithophel’s advice.

35The priests Zadok and Abiathar will be with you there. When you hear anything from the royal palace, tell it to the priests Zadok and Abiathar.

36They have two sons with them: Zadok has Ahimaaz, and Abiathar has Jonathan. Send them to report to me anything you hear.”

37So Hushai, David’s friend, went to the city as Absalom was entering Jerusalem.
