Numbers 4:21-33

The LORD said to Moses, “Count the Gershonites by families and family groups. Count the men from thirty to fifty years old, all who have a job to do in the Meeting Tent. “This is what the Gershonite family groups must do and what they must carry. They must carry the curtains of the Holy Tent, the Meeting Tent, its covering, and its outer covering made from fine leather. They must also carry the curtains for the entrance to the Meeting Tent, the curtains of the courtyard that go around the Holy Tent and the altar, the curtain for the entry to the courtyard, the ropes, and all the things used with the curtains. They must do everything connected with these things. Aaron and his sons are in charge of what the Gershonites do or carry; you tell them what they are responsible for carrying. This is the work of the Gershonite family group at the Meeting Tent. Ithamar son of Aaron, the priest, will direct their work. “Count the Merarite families and family groups. Count the men from thirty to fifty years old, all who work at the Meeting Tent. It is their job to carry the following as they serve in the Meeting Tent: the frames of the Holy Tent, the crossbars, the posts, and bases, in addition to the posts that go around the courtyard, their bases, tent pegs, ropes, and everything that is used with the poles around the courtyard. Tell each man exactly what to carry. This is the work the Merarite family group will do for the Meeting Tent. Ithamar son of Aaron, the priest, will direct their work.”
