Exodus 26:8-10

Darby Translation

⁸ The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits—one measure for the eleven curtains.

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.
