Exodus 27:11 (KJV)

And thou shalt make staves for the altar, staves of shittim wood, and overlay them with brass.

And the staves shall be put into the rings, and the staves shall be upon the two sides of the altar, to bear it.

Hollow with boards shalt thou make it: as it was shewed thee in the mount, so shall they make it.

And thou shalt make the court of the tabernacle: for the south side southward there shall be hangings for the court of fine twined linen of an hundred cubits long for one side:

And the twenty pillars thereof and their twenty sockets shall be of brass; the hooks of the pillars and their fillets shall be of silver.

And for the breadth of the court on the west side shall be hangings of fifty cubits: their pillars ten, and their sockets ten.

And the breadth of the court on the east side eastward shall be fifty cubits.

The hangings of one side of the gate shall be fifteen cubits: their pillars three, and their sockets three.

And on the other side shall be hangings fifteen cubits: their pillars three, and their sockets three.

And for the gate of the court shall be an hanging of twenty cubits, of blue, and purple, and scarlet, and fine twined linen, wrought with needlework: and their pillars shall be four, and their sockets four.
