Numbers 3:26
And the hangings of the court, and the curtain for the door of the court, which is by the tabernacle, and by the altar round about, and the cords of it for all the service thereof. And the hangings of the court, and the curtain for the door of the court, which is by the tabernacle, and by the altar round about, and the cords of it for all the service thereof.
The charge laid out here belongs to the sons of Gershon as their appointed portion of tabernacle service. It entrusted to them the hangings enclosing the court, together with the curtain screening the court entrance and the cords belonging to them. This work formed part of their broader responsibility for the curtains and hangings of the sanctuary.
