Exodus 36:11-13

American Standard Version

¹¹ And he made loops of blue upon the edge of the one curtain ^[a]from the selvedge in the coupling: likewise he made in the edge of the curtain that was outmost in the second ^[b]coupling. 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 ^[c]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.
