2 Samuel 15:27, 35

The king also said to Zadok the priest, “Are you not a seer? Return to the city in peace [you and Abiathar], 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 every word you hear from the king’s palace, you shall report it to them.
