Exodus 38:9-12

And he made the court: for the south side southward the hangings of the court were of fine twined linen, a hundred cubits; their pillars were twenty, and their sockets twenty, of brass; the hooks of the pillars and their fillets were of silver. And for the north side a hundred cubits, their pillars twenty, and their sockets twenty, of brass; the hooks of the pillars, and their fillets, of silver. And for the west side were hangings of fifty cubits, their pillars ten, and their sockets ten; the hooks of the pillars, and their fillets, of silver.
