'Covering' in the Bible
Now the duties of the sons of Gershon in the tent of meeting involved the tabernacle and the tent, its covering, and the screen for the doorway of the tent of meeting,
and they shall lay a covering of porpoise skin on it, and shall spread over it a cloth of pure blue, and shall insert its poles.
They shall spread over them a cloth of scarlet material, and cover the same with a covering of porpoise skin, and they shall insert its poles.
and they shall put it and all its utensils in a covering of porpoise skin, and shall put it on the carrying bars.
Over the golden altar they shall spread a blue cloth and cover it with a covering of porpoise skin, and shall insert its poles;
and they shall take all the utensils of service, with which they serve in the sanctuary, and put them in a blue cloth and cover them with a covering of porpoise skin, and put them on the carrying bars.
When Aaron and his sons have finished covering the holy objects and all the furnishings of the sanctuary, when the camp is to set out, after that the sons of Kohath shall come to carry them, so that they will not touch the holy objects and die. These are the things in the tent of meeting which the sons of Kohath are to carry.
they shall carry the curtains of the tabernacle and the tent of meeting with its covering and the covering of porpoise skin that is on top of it, and the screen for the doorway of the tent of meeting,
Every open vessel, which has no covering tied down on it, shall be unclean.
