Exodus 27:7

4 And thou shalt make for it a grate of network of brass; and upon the net shalt thou make four brasen rings in the four corners thereof.

5 And thou shalt put it under the compass of the altar beneath, that the net may be even to the midst of the altar.

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

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

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

9 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:

10 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.
