Exodus 26:10

⁸The length of one skin thirty cubits, and the breadth of one skin four cubits: there shall be the same measure to the eleven skins.

⁹And thou shalt join the five skins together, and the six skins together; and thou shalt double the sixth skin in front of the tabernacle.

— Exodus 26:10 —

¹¹And thou shalt make fifty brazen rings; and thou shalt join the rings by the loops, and thou shalt join the skins, and they shall be one.

¹²And thou shalt fix at the end that which is over in the skins of the tabernacle; the half of the skin that is left shalt thou fold over, according to the overplus of the skins of the tabernacle; thou shalt fold it over behind the tabernacle.
