Charles Ellicott Commentary Jeremiah 52:21-23

"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. 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. And there were ninety and six pomegranates on the sides; all the pomegranates were a hundred upon the network round about." — Jeremiah 52:21-23 (ASV)

And concerning the pillars ... —In 2 Kings 25:16–17, we have a list abbreviated by the omission of some of the measurements and of the number and arrangement of the pomegranates. "Chapiter" is an older English term for the "capital" of a column.

On a side. —The exact meaning of the Hebrew is towards a (=each) wind — i.e., there were twenty-four pomegranates on each side of the square pillars, with one at each corner, making, as in Jeremiah 52:23, one hundred in all.
