Exodus 26:7-13

7“Make curtains of goat hair for the tent over the tabernacle—eleven altogether. 8All eleven curtains are to be the same size—thirty cubits long and four cubits wide. 9Join five of the curtains together into one set and the other six into another set. Fold the sixth curtain double at the front of the tent. 10Make fifty loops along the edge of the end curtain in one set and also along the edge of the end curtain in the other set. 11Then make fifty bronze clasps and put them in the loops to fasten the tent together as a unit. 12As for the additional length of the tent curtains, the half curtain that is left over is to hang down at the rear of the tabernacle. 13The tent curtains will be a cubit longer on both sides; what is left will hang over the sides of the tabernacle so as to cover it.
