Brief history of the Hebrew People - Did God really divorce them?

How and why they lost their land. "Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled." Luke 21:24 The time of the Gentiles is over when Jesus returns.
Isaiah 50 Judah's Divorce
Deuteronomy 24 If a man marries a woman who becomes displeasing to him because he finds something indecent about her, and he writes her a certificate of divorce, gives it to her and sends her from his house, 2 and if after she leaves his house she becomes the wife of another man, 3 and her second husband dislikes her and writes her a certificate of divorce, gives it to her and sends her from his house, or if he dies, 4 then her first husband, who divorced her, is not allowed to marry her again after she has been defiled. That would be detestable in the eyes of the Lord. Do not bring sin upon the land the Lord your God is giving you as an inheritance.

19 This day I call the heavens and the earth as witnesses against you that I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live 20 and that you may love the Lord your God, listen to his voice, and hold fast to him. For the Lord is your life, and he will give you many years in the land he swore to give to your fathers, Abraham, Isaac and Jacob. Deuteronomy 30
