'Cubits' in the Bible

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.
