Exodus 26:8

6You shall make fifty clasps of gold, and couple the curtains to one another with the clasps. The tabernacle shall be a unit.

7“You shall make curtains of goats’ hair for a covering over the tabernacle. You shall make eleven curtains.

8The length of each curtain shall be thirty cubits, and the width of each curtain four cubits: the eleven curtains shall have one measure.

9You shall couple five curtains by themselves, and six curtains by themselves, and shall double over the sixth curtain in the forefront of the tent.

10You shall make fifty loops on the edge of the one curtain that is outermost in the coupling, and fifty loops on the edge of the curtain which is outermost in the second coupling.
