2 Samuel 15:24-27, 35, 36

Zadok was there, too, and all the Levites who were with him were carrying the ark of the covenant of God. They set down the ark of God, and Abiathar offered sacrifices until all the people had finished leaving the city. Then the king said to Zadok, “Take the ark of God back into the city. If I find favor in the LORD’s eyes, he will bring me back and let me see it and his dwelling place again. But if he says, ‘I am not pleased with you,’ then I am ready; let him do to me whatever seems good to him.” The king also said to Zadok the priest, “Do you understand? Go back to the city with my blessing. Take your son Ahimaaz with you, and also Abiathar’s son Jonathan. You and Abiathar return with your two sons.

Won’t the priests Zadok and Abiathar be there with you? Tell them anything you hear in the king’s palace.

Their two sons, Ahimaaz son of Zadok and Jonathan son of Abiathar, are there with them. Send them to me with anything you hear.”
