And this [is] the charge of their burden,.... What should be committed to their care and charge, and they should bear and carry:
according to all their service in the tabernacle of the congregation; which was assigned to them as their part, and which was very heavy and cumbersome, and therefore they had wagons allowed them, Numbers 7:8;
the boards of the tabernacle, and the bars thereof, and the pillars thereof, and sockets thereof; all these belonged to the holy and to the most holy place; see Exodus 26:15.
