Exodus 36:12-17

12Fifty loops he made in one curtain, and fifty loops he made in the edge of the curtain which was in the coupling of the second: the loops held one curtain to another. 13And he made fifty clasps of gold, and coupled the curtains one to another with the clasps: so it became one tabernacle.

14And he made curtainsofgoats’ hair for the tent over the tabernacle: eleven curtains he made them. 15The length of one curtain was thirty cubits, and four cubits was the breadth of one curtain: the eleven curtains were of one size. 16And he coupled five curtains by themselves, and six curtains by themselves. 17And he made fifty loops upon the outer edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.
