Exodus 26:12 KJV

10And thou shalt make fifty loops on the edge of the one curtain that is outmost in the coupling, and fifty loops in the edge of the curtain which coupleth the second.

11And thou shalt make fifty taches of brass, and put the taches into the loops, and couple the tent together, that it may be one.

12And the remnant that remaineth of the curtains of the tent, the half curtain that remaineth, shall hang over the backside of the tabernacle.

13And a cubit on the one side, and a cubit on the other side of that which remaineth in the length of the curtains of the tent, it shall hang over the sides of the tabernacle on this side and on that side, to cover it.

14And thou shalt make a covering for the tent of rams’ skins dyed red, and a covering above of badgers’ skins.
