2 Samuel 15:34-36

New Revised Standard Version, Anglicised

³⁴ But if you return to the city and say to Absalom, “I will be your servant, O king; as I have been your father’s servant in time past, so now I will be your servant”, then you will defeat for me the counsel of Ahithophel. ³⁵ The priests Zadok and Abiathar will be with you there. So whatever you hear from the king’s house, tell it to the priests Zadok and Abiathar. ³⁶ Their two sons are with them there, Zadok’s son Ahimaaz and Abiathar’s son Jonathan; and by them you shall report to me everything you hear.’
