'Pillar' in the Bible

For, behold, I have made thee this day a defenced city, and an iron pillar, and brasen walls against the whole land, against the kings of Judah, against the princes thereof, against the priests thereof, and against the people of the land.

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.

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.
