Jeremiah 52:21-22

21And as to the pillars: the height of one pillar was eighteen cubits, and a line of twelve cubits encompassed it; and the thickness thereof was four fingers: it was hollow.

22And the capital upon it was brass, and the height of the one capital [was] five cubits; and the network and the pomegranates, upon the capital round about, all of brass; and similarly for the second pillar, and the pomegranates.
