Exodus 38:10

8He made the basin of bronze, and its base of bronze, out of the mirrors of the ministering women who ministered at the door of the Tent of Meeting.

9He made the court: for the south side southward the hangings of the court were of fine twined linen, one hundred cubits;

10their pillars were twenty, and their sockets twenty, of bronze; the hooks of the pillars and their fillets were of silver.

11For the north side one hundred cubits, their pillars twenty, and their sockets twenty, of bronze; the hooks of the pillars, and their fillets, of silver.

12For 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.
