Exodus 36:23
They made twenty boards for the southern side,
Each board was fitted with two matching arms; this they did for all the boards of the Holy Tent.
They made another covering of rams’ skins dyed red to be put over the Holy Tent and a covering of fine leather to spread over that.
They attached fifty loops to the border of the last sheet in the first set and fifty loops to the border of the last sheet in the second set.
The length of a single sheet was thirty cubits, its width four cubits; the eleven sheets were all the same size.
Next, they made sheets of goats’ hair to form a tent over the Holy Tent; they made eleven of these.
