Counter-Arguments

The strongest case that this verse does not belong in this theme.

Symbolic Millennium

The verse uses "thousand" and "ten thousand" as numerical quantities to describe the scale of those falling, not as a symbolic representation of an indefinite period or a completeness of time. The context is about protection from danger, not a specific era.
