The Second Gathering to the land

[Robert]

[...] My point is this: This second gathering, as described by the prophets, does not seem possible if a significant amount of Jews have already returned and are established in the land.

The shocking implication is that Jews will once again be expelled from their land before the second gathering can take place to inaugurate the Messianic Kingdom. [...]

On the Jewish world populations, about just under half reside in the United States:

[...] Israel hosts the largest core Jewish population in the world with 7.2 million,
followed by the United States with 6.3 million. [...]

While the Scriptures prophesy as you point out, that the Jews will be brought back to their ancestral homeland of Israel by G-d, the Scriptures do not prophesy any further exile.


However, the Scriptures also say this:

Yirmiyahu (Jeremiah) 30:16:

[...] all who devour you shall be devoured, and all your adversaries, yea all of them, shall go into captivity, and those who plunder you shall be plunder, and all who prey upon you I will give for prey.
