Under the direction of Aaron and his sons shall be all the service of the sons of the Gershonites, in all they have to carry and in all they have to do; and you shall assign to their charge all that they are to carry [on the march].
And Eleazar son of Aaron the priest shall have charge of the oil for the light, the fragrant incense, the continual cereal offering, and the anointing oil, with the oversight of all the tabernacle and of all that is in it, of the sanctuary and its utensils.
Their charge was to be the ark, the table, the lampstand, the altars, and the utensils of the sanctuary with which the priests minister, and the screen, and all the service having to do with these.
But shall help their brethren in the Tent of Meeting [attend to protecting the sacred things from being profaned], but shall do no regular or heavy service. Thus shall you direct the Levites in regard to their duties.
