John Gill's Exposition of the Whole Bible
Jeremiah 52:22
And a chapiter of brass [was] upon it,.... Or a coronet of brass, of molten brass, was set upon the top of the pillar:
and the height of one chapiter [was] five cubits; as in 1 Kings 7:16; but in 2 Kings 25:17; the height is said to be but three cubits; which is reconciled by the Jewish Rabbins thus, the three superior cubits of it were with ornaments, the two inferior without any; the whole together was five cubits; but, as ornamented, only three:
with network and pomegranates upon the chapiters round about, all [of] brass; the nets were of chequer work, and wreaths of chain work, and there were seven of them to each chapiter, 1 Kings 7:17;
the second pillar also, and the pomegranates, [were] like unto these; one pillar was exactly like the other, and the ornaments of it the same.
