⁴And thou shalt make for them loops of blue on the edge of one curtain, on one side for the coupling, and so shalt thou make on the edge of the outer curtain for the second coupling.

⁵Fifty loops shalt thou make for one curtain, and fifty loops shalt thou make on the part of the curtain answering to the coupling of the second, opposite each other, corresponding to each other at each point.
