Numbers 3:25-26

25Gershon's clan had to take care of the Tent of Meeting, with the cloth that covered it, and the curtain at its door.

26There was a yard round the outside of the tabernacle and the altar. Gershon's family took care of the curtains that hung round the yard, with their ropes. They also took care of the curtain at the entrance to the yard. They took care of all those kinds of things.
