[PatrickHenry]

The verse in Isaiah speaking of "the circle of the earth" uses the word chug, which usually means a disc or ring.

A couple of years ago when that same verse came up, I found an on-line concordance, which not only gives the word's meaning, but it also cites all the other verses where that same word appears. As I recall, the word is never used in the context of a sphere.

I searched Strongs for the word sphere and nothing came up.

H2329 appears only in:
Job 22:14
Prov 8:27
Isa 40:22

No reference to "Lord of the Rings" in any of the passages.
