Exodus 36:9-11

Amplified Bible

⁹ Each curtain was twenty-eight cubits long and four cubits wide; all the curtains were one size. ¹⁰ Bezalel joined five curtains one to another, and [the other] five curtains he joined one to another. ¹¹ He made loops of blue on the edge of the outermost curtain in the first set; he also did this on the edge of the curtain that was outermost in the second set.
