Exodus 38:11 (KJV)

And he made the court: on the south side southward the hangings of the court were of fine twined linen, an hundred cubits:

Their pillars were twenty, and their brasen sockets twenty; the hooks of the pillars and their fillets were of silver.

And for the north side the hangings were an hundred cubits, their pillars were twenty, and their sockets of brass twenty; 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.

And for the east side eastward fifty cubits.
