The only bit I can think of that *might* be used are 2 passages that refer to the "four corners of the Earth":
And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
This is the KJV wording.
I'm trying to dig out of my memory banks what I once read on "Flat Earth" ideas long ago. Ah ha, did a google. Here's something for you:http://www.lhup.edu/~dsimanek/febible.htm
It's a bit odd, but it may give you some data as to how some people could use Scripture in, ah, *different* ways.
To counter this is this page from Jeffrey Burton Russell who wrote an excellent and very readable book Inventing the Flat Earthhttp://www.id.ucsb.edu/fscf/library/RUSSELL/FlatEarth.html
And here's a page about him; he's a historian and has written on Christian subjectshttp://id-www.ucsb.edu/fscf/library/RUSSELL/home.html
I apologize for sounding a bit leery.
