2 Samuel 15:24-27, 35-36

Zadok and all the Levites with him carried the Ark of the Agreement with God. They set it down, and Abiathar offered sacrifices until all the people had left the city. The king said to Zadok, “Take the Ark of God back into the city. If the LORD is pleased with me, he will bring me back and will let me see both it and Jerusalem again. But if the LORD says he is not pleased with me, I am ready. He can do what he wants with me.” The king also said to Zadok the priest, “Aren’t you a seer? Go back to the city in peace and take your son Ahimaaz and Abiathar’s son Jonathan with you.

The priests Zadok and Abiathar will be with you. Tell them everything you hear in the royal palace. Zadok’s son Ahimaaz and Abiathar’s son Jonathan are with them. Send them to tell me everything you hear.”
