Exodus 26:6 KJV

4And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the uttermost edge of another curtain, in the coupling of the second.

5Fifty 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.

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

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

8The 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.
