2 Kings 25:16-17

16The two pillars, the one sea, and the bases which Solomon had made for the house of Jehovah: for the brass of all these vessels there was no weight.

17The height of one pillar was eighteen cubits, and the capital upon it was brass, and the height of the capital three cubits; and the network and the pomegranates, upon the capital round about, all of brass: and similarly for the second pillar with the network.
