Who was to care for the tabernacle curtains, the tent,  the tent covering, the entrance curtain, the courtyard hangings, the courtyard entrance curtain, and the courtyard, ropes, and all that was in the tent of meeting?

The clans of the Gershonites who camped on the west side of the tabernacle were to care for the tabernacle coverings, curtain, and ropes. [3:25; 3:26]
