Numbers 4:21

“When Aaron and his sons have finished covering the sanctuary and all the furniture of the sanctuary, as the camp moves forward; after that, the sons of Kohath shall come to carry it; but they shall not touch the sanctuary, lest they die. The sons of Kohath shall carry these things belonging to the Tent of Meeting.

“This is the service of the families of the Gershonites, in serving and in bearing burdens:

This is the duty of their burden, according to all their service in the Tent of Meeting: the tabernacle’s boards, its bars, its pillars, its sockets,

According to the commandment of Yahweh they were counted by Moses, everyone according to his service and according to his burden. Thus they were counted by him, as Yahweh commanded Moses.

But the Levites after the tribe of their fathers were not counted among them.

Thus the children of Israel did. According to all that Yahweh commanded Moses, so they did.

But the Levites were not counted among the children of Israel, as Yahweh commanded Moses.

Moses counted them according to Yahweh’s word, as he was commanded.

These are those who were counted of the families of the Kohathites, all who served in the Tent of Meeting, whom Moses and Aaron counted according to the commandment of Yahweh by Moses.

These are those who were counted of the families of the sons of Gershon, all who served in the Tent of Meeting, whom Moses and Aaron counted according to the commandment of Yahweh.

These are those who were counted of the families of the sons of Merari, whom Moses and Aaron counted according to the commandment of Yahweh by Moses.

Also the Levites will no longer need to carry the tabernacle and all its vessels for its service.”
