Exodus 36:16 (KJV)

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.

Fifty 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.

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 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.

And he made fifty taches of brass to couple the tent together, that it might be one.

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

And he made boards for the tabernacle of shittim wood, standing up.

The length of a board was ten cubits, and the breadth of a board one cubit and a half.
