Matthew Poole and continuators on 1 Kings 7:16

16 And he made two chapiters of molten brass, to set upon the tops of the pillars: the height of the one chapiter was five cubits , and the height of the other chapiter was five cubits.

Obj. It is but three cubits in 2 King. 25. 17. Ans. The word chapiter is taken diversly, as hundreds of other words are, either more largely for the whole, so it is 5 Cubits; or, more strictly, either for the pommels, as they are called, 2 Chron. 4. 12. or for the Cornice or Crown, and so it was but three Cubits, to which the Pomegranates being added make it four cubits, as it is below, ver. 19. and the other work upon it took up one Cubit more, which in all made five cubits.
