Numbers 4:25-27

25The men from that clan must carry the curtains of God's Tent. And they must carry the Tent of Meeting with the thing that covers it. And they must carry the good leather that covers all that. And they must carry the curtain for the place where people go into the Tent of Meeting.

26They must carry the curtains of the yard that is round God's Tent. Also, they must carry the curtain and ropes for the place where people go into the yard. That is the yard that is round God's Tent and the altar. The men from Gershon's clan must carry all the tools that belong with those curtains. They must do everything that all those things need.

27The men in Gershon's clan must do everything that Aaron and his sons ask them to do. Aaron and his sons must tell them the things that they should carry. And they must tell them everything that they should do.
