Exodus 36:12 (KJV)

For the stuff they had was sufficient for all the work to make it, and too much.

And every wise hearted man among them that wrought the work of the tabernacle made ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubims of cunning work made he them.

The length of one curtain was twenty and eight cubits, and the breadth of one curtain four cubits: the curtains were all of one size.

And he coupled the five curtains one unto another: and the other five curtains he coupled one unto another.

And he made loops of blue on the edge of one curtain from the selvedge in the coupling: likewise he made in the uttermost side of another curtain, in the coupling of the second.

And he made fifty taches of gold, and coupled the curtains one unto another with the taches: so it became one tabernacle.

And he made curtains of goats' hair for the tent over the tabernacle: eleven curtains he made them.

The length of one curtain was thirty cubits, and four cubits was the breadth of one curtain: the eleven curtains were of one size.

And he coupled five curtains by themselves, and six curtains by themselves.

And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.
