Exodus 36:11

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.

Then they made loops of blue material along the edge of the end curtain in one set, and the same was done with the end curtain in the other set.

He made loops of blue yarn on the edge of the last curtain in the first set and did the same on the edge of the outermost curtain in the second set.

He made fifty loops of blue yarn and put them along the edge of the last curtain in each set.

And he made loops of blue on the edge of the one curtain, at the end in the set; so he did on the edge of the end curtain in the second set.

And he made loops of blue on the edge of one curtain from the selvedge in the coupling: likewise he made in the uttermost side of another curtain, in the coupling of the second.
