Exodus 26:12
Brenton's English Septuagint · Berean Standard Bible
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.
As for the overlap that remains of the tent curtains, the half curtain that is left over shall hang down over the back of the tabernacle.
