Exodus 36:12-15 American Standard Version (ASV)

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

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

14. And he made curtains of goats’ hair for a tent over the tabernacle: eleven curtains he made them.

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