Exodus 38:9KJV

7And he put the staves into the rings on the sides of the altar, to bear it withal; he made the altar hollow with boards.

8And he made the laver brass, and the foot of it brass, of the lookingglasses of assembling, which assembled the door of the tabernacle of the congregation.

9And he made the court: on the south side southward the hangings of the court fine twined linen, an hundred cubits:

10Their pillars twenty, and their brasen sockets twenty; the hooks of the pillars and their fillets silver.

11And for the north side an hundred cubits, their pillars twenty, and their sockets of brass twenty; the hooks of the pillars and their fillets silver.
