eighteen cubits
As in ( 1 Kings 7:15 ) ; said to be thirty five, ( 2 Chronicles 3:15 ) ; of the reconciliation of which, (See Gill on 2 Chronicles 3:15): and a fillet of twelve cubits did compass it;
a thread or line of that measure encompassed each of the pillars, ( 1 Kings 7:15 ) ; and the thickness thereof [was] four fingers;

Jeremiah 52:21 In-Context

19 And the basons and the censers, and the bowls, and the pots, and the candlesticks, and the cups, and the goblets, that which was of gold in gold, and that which was of silver in silver, the captain of the body-guard took away.
20 The two pillars, the one sea, and the twelve brazen oxen that formed the bases, which king Solomon had made for the house of Jehovah: for the brass of all these vessels there was no weight.
21 And 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.
22 And 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.
23 And there were ninety-six pomegranates on the [four] sides; all the pomegranates upon the network were a hundred round about.
