Exodus 27:7

4 And thou shalt make for it a grating of network of brass: and upon the net shalt thou make four brazen rings in the four corners thereof.

5 And thou shalt put it under the ledge round the altar beneath, that the net may reach halfway up the altar.

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

7 And the staves thereof shall be put into the rings, and the staves shall be upon the two sides of the altar, in bearing it.

8 Hollow with planks shalt thou make it: as it hath been showed 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 a hundred cubits long for one side:

10 and the pillars thereof shall be twenty, and their sockets twenty, of brass; the hooks of the pillars and their fillets [shall be] of silver.
