Exodus 38:9-12

And he made the court. For the south side the hangings of the court were of fine twined linen, a hundred cubits; their twenty pillars and their twenty bases were of bronze, but the hooks of the pillars and their fillets were of silver. And for the north side there were hangings of a hundred cubits; their twenty pillars and their twenty bases were of bronze, but the hooks of the pillars and their fillets were of silver. And for the west side were hangings of fifty cubits, their ten pillars, and their ten bases; the hooks of the pillars and their fillets were of silver.
