Amo 9:15 And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God.
There is no way anyone could construe this to mean this event took place in the past...
Tell that to James and Peter. They were ones who took Amos 9 and applied it to contemporary events in their day.
Maybe they were not "literalists". Maybe they saw the true spiritual fulfillment of the prophecies.
