Exodus 36:12-17

12He made fifty loops on the one curtain, and he made fifty loops on the edge of the curtain that was in the second set. The loops were opposite one another.

13And he made fifty clasps of gold, and coupled the curtains one to the other with clasps. So the tabernacle was a single whole.

14He also made curtains of goats' hair for a tent over the tabernacle. He made eleven curtains.

15The length of each curtain was thirty cubits, and the breadth of each curtain four cubits. The eleven curtains were the same size.

16He coupled five curtains by themselves, and six curtains by themselves.

17And he made fifty loops on the edge of the outermost curtain of the one set, and fifty loops on the edge of the other connecting curtain.
