2 Samuel 15:25-29

Then the king instructed Zadok to take the Ark of God back into the city. “If the LORD sees fit,” David said, “he will bring me back to see the Ark and the Tabernacle again. But if he is through with me, then let him do what seems best to him.” The king also told Zadok the priest, “Look, here is my plan. You and Abiathar should return quietly to the city with your son Ahimaaz and Abiathar’s son Jonathan. I will stop at the shallows of the Jordan River and wait there for a report from you.” So Zadok and Abiathar took the Ark of God back to the city and stayed there.
