There are many appropriate Scriptural references, including the following:
"Section 29:14 and there shall be greater signs in heaven above and in the earth beneath;"
That doesn't really claim the Earth is Hollow. It's clearly one of the many references to the Earth being below the sky, not an indication that there's a civilization inside the Earth.
Given then structure of the passage, if you read it to claim the Earth is Hollow, then it is stating that signs will be found in Heaven, and in the subterranean civilization, but
not on the surface where we live.
"Section 45:40 And they shall see signs and wonders, for they shall be shown forth in the heavens above, and in the earth beneath.
Section 88:79 Of things both in heaven and in the earth, and under the earth;"
Both of these fall into the same category as the passage above. Earth is below the sky, and this relationship is mentioned frequently in scripture. Claiming this frequent mention of an obvious physical reality as evidence of a subterranean civilization is, to be kind, comically absurd.
"Section 84:100 The Lord hath brought down Zion from above. The Lord hath brought up Zion from beneath. 101 The earth hath travailed and brought forth her strength; And truth is established in her bowels;"
"Section 101:34 Things most precious, things that are above, and things that are beneath, things that are in the earth, and upon the earth, and in heaven."
Again, common biblical and Bible style hyperbole is being portrayed as evidence of something for which there is NO physical evidence, or any explicit claims in scripture, Mormon, Protestant or Catholic.
Frankly, if this is the best "evidence" for a Hollow Earth in Mormon scripture, then it's clear there's no scriptural support for the idea to speak of.
