'Curtain' in the Bible

The duties of the descendants of Gershon at the Tent of Meeting pertained to the tent, the tent covering, the curtain to the entrance to the Tent of Meeting,

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 their charge was the ark, and the table, and the candlestick, and the altars, and the utensils of the sanctuary with which they ministered, and the curtain, and all that belongs to its service.

When the camp is about to travel, Aaron and his sons are to come and take down the veil of the curtain and cover the Ark of the Testimony with it.

They are to carry the curtain of the tent, the covering of the Tent of Meeting, the dyed leather covering that goes over it, the curtain for the entrance to the Tent of Meeting,

the hangings for the courtyard, the curtain for the entrance to the gate of the courtyard that surrounds the tent, the altar, the ropes, all the service utensils, and everything made for them. This is to be their service area.

But you and your sons with you are responsible for your priestly duties, for everything at the altar and within the curtain. And you must serve. I give you the priesthood as a gift for service; but the unauthorized person who approaches must be put to death."
