Exodus 36:14

12Fifty loops made he in one curtain, and fifty loops made he 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 taches of gold, and coupled the curtains one unto another with the taches: so it became one tabernacle.

14And he made curtains of goats’ 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.
