He told the Levites, who instructed all Israel and performed ceremonies to make themselves holy to the Lord, “Put the holy ark in the temple that Solomon, son of David and king of Israel, built. It shouldn’t be carried on your shoulders any longer. Serve the Lord your God and his people Israel.
But Moses gave none of these gifts to the Kohathites, because they took care of the holy things. They had to carry the holy things on their own shoulders.
At that time the Lord set apart the tribe of Levi to carry the ark of the Lord’s promise, to stand in the Lord’s presence when they serve him as priests, and to praise his name, as they still do today.
They told the people, “As soon as you see the ark of the promise of the Lord your God and the Levitical priests who carry it, break camp and follow them.
Joshua, son of Nun, summoned the priests. He said to them, “Pick up the ark of the promise, and have seven priests carry seven rams’ horns ahead of the Lord’s ark.”
