2 Samuel 15:35-39

Are Zadok and Abiathar the priests not with you there? So it shall be that whatever you hear from the king’s house, you shall report to Zadok and Abiathar the priests.

Behold their two sons are there with them, Ahimaaz, Zadok’s son and Jonathan, Abiathar’s son; and by them you shall send me everything that you hear.”

So Hushai, David’s friend, came into the city, and Absalom came into Jerusalem.
