Amos 9:14-15 "I will bring back the captives of My people Israel; They shall build the waste cities and inhabit them; They shall plant vineyards and drink wine from them; They shall also make gardens and eat fruit from them. I will plant them in their land, And no longer shall they be pulled up From the land I have given them," Says the Lord your God."
So after the Diasporas, if the Jews are blessings to those nations, then they will have peace and prosperity. But if they were once again wicked, selfish, covetous (causing great misery with high interest rates in Europe) and oppose the Gospel (Crusades in Europe), then they will be displaced, killed and also suffer great losses until God called them back to form Israel.
On 13 July 1878 at the Treaty of Berlin, the only British Prime Minister Benjamin Disraeli with Hebrew linage, secured the control of the middle East and Palestine on behalf of the dying Ottoman dynasty. Immediately, he allowed Jews to buy land in Palestine. This started the call of 'Aliyah' back to rebuild Zion, the nation of Israel. Palestine then was mainly desert and wasteland, desolated by God to give the land its sabbath with only 300K people.
Exo 23:29 "I will not drive them out from before you in one year, lest the land become desolate and the beasts of the field become too numerous for you."
Two million Hebrews entered the Promised Land under Joshua, yet God did not give it to them in one year because the population was too low.
So, had more than two million Jews aliyah out of the tens of millions, then Israel would have been formed by 1900 for in the 1917 Balfour Declaration, the Jews was given Syria Palestina to form their new nation Israel. God again handed the promised land to the Jews on the platter but less than 20K aliyah by 1882 (what a shame!). So God could not allow that unbelieving generation of Jews to form the new nation of Israel.
Ezek 33:31 "So they come to you as people do, they sit before you as My people, and they hear your words, but they do not do them; for with their mouth they show much love, but their hearts pursue their own gain."
The Lord told us that the Jews want to seek His will, but they will not keep it for they are really faithless and stiff necked and are real hypocrites. The Jews were enjoying their lives in their new foster nations and refused to aliyah back to form Israel.
Unbelief of the Jews
Immediately, after the Jews were allowed to buy land in 1878, God allowed pogroms in Czarist Russia in 1881-84 and again in 1903-06 with many Jews raped, murdered and land confiscated resulting to 2 million Jews from 1880 to 1914 migrated to UK and US, but only a few (less than 40K) aliyah to Palestine. Where is the love for their homeland? Hypocrites!
Similarly, God used many pogroms in the 1920s and 30s in Europe to force the Jews to aliyah to escape death but these Jews migrated to third countries.
Palestine Jews Non Jews
1517 AD 5K 295K
1882 AD 24K 276K
1918 AD 60K 600K
1931 AD 174K 861K
1936 AD 384K 983K
1946 AD 543K 1,267K
God allowed all these pogroms killing millions of Jews otherwise the new nation of Israel could not be formed in 1948.
Similarly, Christians are so comfortable in this world that they refuse to prepare themselves to aliyah to their eternal home (heaven). It will be too late when World War 3 (pogrom) comes, destroying everything and killing 1/4 of all mankind.
