Exodus 26:6-11

6And thou shalt make fifty clasps of gold, and couple the curtains together with the clasps, that the tabernacle may be one [whole].

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

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

9And 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.

10And 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.

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