Exodus 36:12-16

He made fifty loops in the one curtain, and he made fifty loops on the edge of the curtain that was in the second set; the loops were opposite each other.

He also made fifty clasps of gold, and joined the curtains to one another with the clasps, so that the tabernacle was a unit.

Then he made curtains of goats’ hair for a tent over the tabernacle; he made eleven curtains in all.

The length of each curtain was thirty cubits, and four cubits was the width of each curtain; the eleven curtains had the same measurements.

He joined five curtains by themselves, and the other six curtains by themselves.
