2 Samuel 15:34-36

Amplified Bible

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 the past, so I will be your servant now;’ then you can thwart (make useless) the advice of Ahithophel for me. ³⁵ Are not Zadok and Abiathar the priests with you there? So it shall be that every word you hear from the king’s palace, you shall report it to them. ³⁶ Their two sons are there with them, Ahimaaz, Zadok’s son and Jonathan, Abiathar’s son; and by them you shall send to me everything that you hear.”
