Exodus 26:5-9

Fifty loops shalt thou make in the one curtain, and fifty loops shalt thou make in the edge of the curtain that is in the coupling of the second; that the loops may take hold one of another.

And thou shalt make fifty taches of gold, and couple the curtains together with the taches: and it shall be one tabernacle.

And thou shalt make curtains of goats’ hair to be a covering upon the tabernacle: eleven curtains shalt thou make.

The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits: and the eleven curtains shall be all of one measure.

And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double the sixth curtain in the forefront of the tabernacle.
