Exodus 36:14-19

14And he made curtains of goats' [hair] for the tent over the tabernacle: eleven curtains did he make them.

15The length of one curtain was thirty cubits, and four cubits the breadth of one curtain — one measure for the eleven curtains.

16And he coupled five of the curtains by themselves, and six of the curtains by themselves.

17And he made fifty loops on the edge of the outermost curtain in the coupling, and fifty loops made he on the edge of the curtain in the other coupling.

18And he made fifty clasps of copper to couple the tent, that it might be one.

19And he made a covering for the tent [of] rams' skins dyed red, and a covering of badgers' skins above [that].
