Numbers 4:26

and the hangings of the court and the screen for the entrance of the gate of the court that is around the tabernacle and the altar , and their cords and all the equipment for their service . And they shall do all that needs to be done with regard to them.

the curtains of the courtyard surrounding the tabernacle and altar, the curtain for the entrance to the courtyard, the ropes and all the equipment used in the service of the tent. The Gershonites are to do all that needs to be done with these things.

And the hangings of the court, and the hanging for the door of the gate of the court, which is by the tabernacle and by the altar round about, and their cords, and all the instruments of their service, and all that is made for them: so shall they serve.
