Exodus 38:9

He made the poles of acacia wood, and overlaid them with bronze.

He put the poles into the rings on the sides of the altar, with which to carry it. He made it hollow with planks.

He 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.

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

For 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.

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.
