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;

that is, the pillar was hollow.

Jeremiah 52:21 In-Context

19 The cups, and the fire pans, and the basins, and the pots, and the menorot, and the spoons, and the bowls-that which was of gold, in gold, and that which was of silver, in silver,-the captain of the guard took away.
20 The two pillars, the one sea, and the twelve brazen bulls that were under the bases, which king Shlomo had made for the house of the LORD. The brass of all these vessels was without weight.
21 As for the pillars, the height of the one pillar was eighteen cubits; and a line of twelve cubits did compass it; and the thickness of it was four fingers: it was hollow.
22 A capital of brass was on it; and the height of the one capital was five cubits, with network and pomegranates on the capital round about, all of brass: and the second pillar also had like these, and pomegranates.
23 There were ninety-six pomegranates on the sides; all the pomegranates were one hundred on the network round about.
