⁸ The length of each curtain shall be thirty cubits, and the breadth of each curtain four cubits; the eleven curtains shall have the same measure. ⁹ And you shall couple five curtains by themselves, and six curtains by themselves, and the sixth curtain you shall double over at the front of the tent. ¹⁰ And you shall make fifty loops on the edge of the curtain that is outmost in one set, and fifty loops on the edge of the curtain which is outmost in the second set.
