Exodus 36:11-13

English Standard Version

¹¹ He made loops of blue on the edge of the outermost curtain of the first set. Likewise he made them on the edge of the outermost 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 a single whole.
