Exodus 36:13

And he made fifty clasps of gold , and coupled the curtains one to the other with clasps . So the tabernacle was a single whole .

Then they made fifty gold clasps and used them to fasten the two sets of curtains together so that the tabernacle was a unit.

And he made fifty taches of gold, and coupled the curtains one unto another with the taches : so it became one tabernacle.
