'Cubits' in the Bible

Now the pillars, [the] height of one pillar [was] eighteen cubits, and a thread of twelve cubits surrounded it, and its thickness [was] four fingers, hollowed out.

And a capital upon it [was] bronze and the height of the one capital [was] five cubits, and latticework and pomegranates [were] on the capital on all sides, all [of] bronze. And like these [was] the second pillar with pomegranates.
