⁹ And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double over the sixth curtain in the forefront of the tent. ¹⁰ And thou shalt make fifty loops on the edge of the one curtain that is outmost in the ^[a]coupling, and fifty loops upon the edge of the curtain which is outmost in the second ^[b]coupling. ¹¹ And thou shalt make fifty clasps of brass, and put the clasps into the loops, and couple the tent together, that it may be one.
