Exodus 36:14

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

13He made fifty clasps of gold, and coupled the curtains to one another with the clasps: so the tabernacle was a unit.

14He made curtains of goats’ hair for a covering over the tabernacle. He made them eleven curtains.

15The length of each curtain was thirty cubits, and four cubits the width of each curtain. The eleven curtains had one measure.

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