Exodus 27:7

You shall make a grating for it of network of bronze. On the net you shall make four bronze rings in its four corners.

You shall put it under the ledge around the altar beneath, that the net may reach halfway up the altar.

You shall make poles for the altar, poles of acacia wood, and overlay them with bronze.

You shall make it hollow with planks. They shall make it as it has been shown you on the mountain.

“You shall make the court of the tabernacle: for the south side southward there shall be hangings for the court of fine twined linen one hundred cubits long for one side.

Its pillars shall be twenty, and their sockets twenty, of bronze. The hooks of the pillars and their fillets shall be of silver.
