Exodus 27:9-12

And thou shalt make the court of the tabernacle: for the south side southward there shall be hangings for the court of fine twined linen a hundred cubits long for one side: and the pillars thereof shall be twenty, and their sockets twenty, of brass; the hooks of the pillars and their fillets shall be of silver. And likewise for the north side in length there shall be hangings a hundred cubits long, and the pillars thereof twenty, and their sockets twenty, of brass; the hooks of the pillars, and their fillets, of silver. And for the breadth of the court on the west side shall be hangings of fifty cubits; their pillars ten, and their sockets ten.
