2 Samuel 15:24-25

24Zadok 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.

25Then 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.
