'Cubits' in the Bible

As to the pillars, eighteen cubits is the height of the one pillar, and a cord of twelve cubits doth compass it, and its thickness is four fingers hollow.

And the chapiter upon it is of brass, and the height of the one chapiter is five cubits, and net-work and pomegranates are on the chapiter round about, the whole is of brass; and like these have the second pillar, and pomegranates.
