17 The Lord said to Moses and Aaron,
18 “Do not let the clan of Kohath
19 be killed by coming near these most sacred objects. To prevent this happening, Aaron and his sons shall go in and assign each man his task and tell him what to carry.
20 But if the Kohathites enter the Tent and see the priests preparing the sacred objects for moving, they will die.”
21 The Lord told Moses
22 to take a census of the Levite clan of Gershon by sub-clans and families,
23 and to register all the men between the ages of thirty and fifty who were qualified to work in the Tent of the Lord's presence.
