Then David said, “No one should carry the Ark of God except the Levites, for Adonai has chosen them to carry the Ark of Adonai and to serve Him forever.”
For their duty was to help the descendants of Aaron in the avodah of Adonai’s House concerning the courtyards and rooms, the purification of all holy things and the performance of the avodah of God’s House,
They appointed the kohanim in their divisions and the Levites in their divisions over the service of God at Jerusalem, as it is written in the book of Moses.
See, I have given all the tithes in Israel to the sons of Levi as an inheritance in return for all the work of the service they are doing in the Tent of Meeting.
Then the Tent of Meeting will move out with the camp of the Levites, which is in the middle of the camps—just as they were in camp, each person in his own place under his own appropriate standard.
At that time Adonai set the tribe of Levi apart to carry the Ark of the Covenant of Adonai, to stand before Adonai to serve Him and to pronounce blessings in His Name—as is the case to this day.
