Exodus 26:9-11

New King James Version

⁹ And you shall couple five curtains by themselves and six curtains by themselves, and you shall double over the sixth curtain at the forefront of the tent. ¹⁰ You shall make fifty loops on the edge of the curtain that is outermost in one set, and fifty loops on the edge of the curtain of the second set. ¹¹ And you shall make fifty bronze clasps, put the clasps into the loops, and couple the tent together, that it may be one.
