17 Yahweh spoke to Moses and to Aaron, saying,
18 “Don’t cut off the tribe of the families of the Kohathites from among the Levites;
19 but thus do to them, that they may live, and not die, when they approach to the most holy things: Aaron and his sons shall go in, and appoint them everyone to his service and to his burden;
20 but they shall not go in to see the sanctuary even for a moment, lest they die.”
21 Yahweh spoke to Moses, saying,
22 “Take a census of the sons of Gershon also, by their fathers’ houses, by their families;
23 you shall count them from thirty years old and upward until fifty years old; all who enter in to wait on the service, to do the work in the Tent of Meeting.
