Exodus 26:7

⁵  Fifty loops shalt thou make in the one curtain, and fifty loops shalt thou make in the edge of the curtain that is in the coupling of the second; that the loops may take hold one of another.

⁶  And thou shalt make fifty taches of gold, and couple the curtains together with the taches: and it shall be one tabernacle.

⁷  And thou shalt make curtains of goats' hair to be a covering upon the tabernacle: eleven curtains shalt thou make.

⁸  The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits: and the eleven curtains shall be all of one measure.

⁹  And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double the sixth curtain in the forefront of the tabernacle.
