2 Samuel 15:33-37

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

34Return to Jerusalem and tell Absalom, ‘I will now be your adviser, O king, just as I was your father’s adviser in the past.’ Then you can frustrate and counter Ahithophel’s advice.

35Zadok and Abiathar, the priests, will be there. Tell them about the plans being made in the king’s palace,

36and they will send their sons Ahimaaz and Jonathan to tell me what is going on.”

37So David’s friend Hushai returned to Jerusalem, getting there just as Absalom arrived.
