Exodus 36:11-13

Revised Standard Version Catholic Edition

¹¹ And he made loops of blue on the edge of the outmost curtain of the first set; likewise he made them on the edge of the outmost curtain of the second set; ¹² he 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. ¹³ And he made fifty clasps of gold, and coupled the curtains one to the other with clasps; so the tabernacle was one whole.
