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 cups, and the firepans, and the basins, and the pots, and the candlesticks, 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 Solomon had made for the house of Jehovah--the brass of all these vessels was without weight.
21 And 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 thereof was four fingers: it was hollow.
22 And a capital of brass was upon it; and the height of the one capital was five cubits, with network and pomegranates upon the capital round about, all of brass: and the second pillar also had like unto these, and pomegranates.
23 And there were ninety and six pomegranates on the sides; all the pomegranates were a hundred upon the network round about.
