Might start with the book of Joel called a Minor Prophet. Peter made Joel part of the Gospel in the book of Acts.
I have studied for more that three decades ... It is absolutely impossible to in mere moments cite the relevant Scriptures that Christ said He had foretold all things before the New Testament ever got put on plant fibers or animal skins. Now that is not my ‘ego’ talking, because I was dumber than a stump when I started.
Those that claim they come in the name of Christ have far more culpability than the unlearned uncivilized barbarians... In this particular case it is those calling themselves ‘holy’ in Jesus name that are moving these peoples and charging US to do so...
You did not specify what you were referring to "was prophesied".
I understand it could be a rather wide appraisal of conditions, with perhaps a few details serving as way-points -- but -- what are we looking for here? A collection of needles in a haystack, or some lost bricks from an old wall?
I had backtracked in this thread prior to first commenting, trying to see if I could find clear mention -- or even strong hint (if it were direct enough) of what you could be talking about more precisely --- but other than the subject being "immigration" there wasn't much to go on
How about if it's so clear to you what you were talking about --- that you organize that into some kind of flow? Provide an outline, or executive summary of key points perhaps, then if desired to better establish those, show from where in the Bible you may be (in your own mind) have gathered those things together?
Until then this is an almost complete waste of time.
