One of these people cited the following:

The 2017 eclipse passed over many small towns named "Salem".

"Salem Witch Trials". 2017 was the era when social media locked down hard and the many legal and political persecutions of Trump and his administration began in earnest. They make the case that so many "Salems" predicted the kind of legal environment we started to see form in 2017.

The 2024 eclipse passed over about a dozen small towns named "Nineveh".

The symbolism here is that Nineveh in the Bible was a place of repentance. These prophet people consider this as signal that America will be reborn.
