Numbers 4:28

This is the service of the families of the sons of Gershon ,.... Which they should execute when the camp and tabernacle were in motion:

in the tabernacle of the congregation in the court ; where they should take up their burdens, or which lie in things respecting the tabernacle; this was the part they were to be employed in, namely, in taking care of the hangings of the tabernacle, &c.;

and their charge shall be under the hand of Ithamar the son of Aaron the priest ; the things committed to their care were delivered by him to them, and they were under his inspection and direction.
