Exodus 26:4

Make loops of blue material on the edge of the end curtain in the first set, and do the same for the end curtain in the second set.

And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the uttermost edge of another curtain, in the coupling of the second.

Note selvedge: an edge of cloth so woven that it cannot unravel

You shall make loops of blue on the edge of the one curtain from the edge in the coupling, and you shall do likewise on the edge of the curtain that is outermost in the second coupling.

And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the edge of the curtain that is outmost in the second coupling.
