Exodus 26:12

And thou shalt fix at the end that which is over in the skins of the tabernacle; the half of the skin that is left shalt thou fold over, according to the overplus of the skins of the tabernacle; thou shalt fold it over behind the tabernacle.

And the remnant that remaineth of the curtains of the tent, the half curtain that remaineth, shall hang over the backside of the tabernacle.

The overhanging part that remains of the curtains of the tent—the half curtain that remains—shall hang over the back of the tabernacle.
