Exodus 26:9 DBY

⁷  And thou shalt make curtains of goats' [hair] for a tent over the tabernacle: eleven curtains shalt thou make them.

⁸  The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits -- one measure for the eleven curtains.

⁹  And thou shalt couple five of the curtains by themselves, and six of the curtains by themselves, and shalt double the sixth curtain in the front of the tent.

¹⁰  And thou shalt make fifty loops on the edge of the outermost curtain of the coupling, and fifty loops on the edge of the curtain in the other coupling.

¹¹  And thou shalt make fifty clasps of copper, and put the clasps into the loops, and couple the tent, that it may be one [whole].
