Exodus 27:10-12

Its twenty pillars and their twenty bases shall be of bronze, but the hooks of the pillars and their fillets shall be of silver. And likewise for its length on the north side there shall be hangings a hundred cubits long, its pillars twenty and their bases twenty, of bronze, but the hooks of the pillars and their fillets shall be of silver. And for the breadth of the court on the west side there shall be hangings for fifty cubits, with ten pillars and ten bases.
