Darby Translation

⁹ And thou shalt couple five of the curtains by themselves, and six of the curtains by themselves, and shalt double the sixth curtain in the front of the tent.

¹⁰ And thou shalt make fifty loops on the edge of the outermost curtain of the coupling, and fifty loops on the edge of the curtain in the other coupling.

¹¹ And thou shalt make fifty clasps of copper, and put the clasps into the loops, and couple the tent, that it may be one [whole].
