2 Samuel 15:27, 35

The king said also to Zadok the priest, “Are you not a seer? Return to the city in peace and your two sons with you, your son Ahimaaz and Jonathan the son of Abiathar.

Are not Zadok and Abiathar the priests 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.
