Exodus 36:17

And he made fifty loops on the edge of the outermost curtain of the one set , and fifty loops on the edge of the other connecting curtain .

Then they made fifty loops along the edge of the end curtain in one set and also along the edge of the end curtain in the other set.

And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.
