The trees were cut down and the land was salted in 71 AD. A promise that is based on the oath of God, not on the behavior of Israel. The Lord said to Abram, after Lot had separated from him, "Now lift up your eyes and look from the place where you are, northward and southward and eastward and westward; for all the land which you see I will give it to you and to you forever.In 66 AD the Romans robbed the temple treasury and the Jews revolted for 3.5 years. The Persians (Parthians) help the Hasmonean king Antigonus to take Jerusalem back from the Romans. And I will make your descendants as the dust of the earth, so that if anyone can number the dust of the earth then your descendants can also be numbered. Arise, walk about the land through the length and breadth, for I will give it to you." While There Are Heavens Above.
As the promise lingered and Abraham remained childless, he had a son, Ishmael, by the maid of his wife Sarah. Over 600,000 emigrated to Israel, some leaving communities that were 2500 years old.
Ishmael became the father of the Arab nations east of Israel. Jacob tricked Esau into giving up the birthright and he became the heir of the promise. When they finally recognized their brother and went back to their father, Israel migrated to Egypt with about 70 members of the tribe as honored guests because Joseph was the governor of Egypt. It was destroyed by Babylon in 586 BC (587 BCE) on Tisha b'Av (9th of Av) by Nebuchadnezzar II (2 Kings 25). Thousands immigrate from Yemen with Operation Magic Carpet. The creation of the state of Israel immediately provoked a war and a Palestinian exodus.
2 million Russian Jews emigrated between 1881-1920.
Some are forced to convert to Christianity, some emigrate to Jerusalem and other countries and tens of thousands die. The 1882 assassination of tsar Alexander II is followed by vicious physical attacks (Pogroms) against the Russian Jews.
The ten northern tribes were conquered by Assyria and assimilated. That victory never came because God wanted them back in the land. Before the Hebrews possessed the land around 1500 BC, it was occupied by seven nations who were driven out.
