'Veil' in the Bible

In the Tent of meeting, the Gershonites are to have the care of the House, and the Tent with its cover, and the veil for the door of the Tent of meeting,

In their care are the ark, and the table, and the lights, and the altars, and all the vessels used in the holy place, and the veil, and all they are used for.

When all the people go forward, Aaron is to go in with his sons, and take down the veil of the curtain, covering the ark of witness with it;

And you and your sons with you are to be responsible as priests for the altar and everything on it, and everything inside the veil; you are to do the work of priests; I have given you your position as priests; and any other man who comes near will be put to death.
