Jeremiah 52:21

And [concerning] the pillars, the height of one pillar [was]
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;
either of the pillar, or the fillet about it; that is, the brass of it was four fingers thick: [it was] hollow;
that is, the pillar was hollow.

Jeremiah 52:21 In-Context

19 And the basons, and the firepans, and the bowls, and the caldrons, and the candlesticks, and the spoons, and the cups; that which was of gold in gold, and that which was of silver in silver, took the captain of the guard away.
20 The two pillars, one sea, and twelve brasen bulls that were under the bases, which king Solomon had made in the house of the LORD: the brass of all these vessels was without weight.
21 And concerning the pillars, the height of one pillar was eighteen cubits; and a fillet of twelve cubits did compass it; and the thickness thereof was four fingers: it was hollow.
22 And a chapiter of brass was upon it; and the height of one chapiter was five cubits, with network and pomegranates upon the chapiters round about, all of brass. The second pillar also and the pomegranates were like unto these.
23 And there were ninety and six pomegranates on a side; and all the pomegranates upon the network were an hundred round about.
