Parallel
Exodus 26:13
Brenton's English Septuagint · Berean Standard Bible
A cubit on this side, and a cubit on that side of that which remains of the skins, of the length of the skins of the tabernacle: it shall be folding over the sides of the tabernacle on this side and that side, that it may cover it.
And the tent curtains will be a cubit (note: A cubit is approximately 18 inches or 45.7 centimeters.) longer on either side, and the excess will hang over the sides of the tabernacle to cover it.
