This is found in Jeremiah 3:8 (NIV)
I gave faithless Israel her certificate of divorce and sent her away because of all her adulteries. Yet I saw that her unfaithful sister Judah had no fear; she also went out and committed adultery.
Following the judgment of being put in other nations was Israel subjected to obey the laws and culture of the land? This question is more from a historical view. Is Israel divorced from God but can be brought back by Christ the Groom? Which is seen in the return of the nation at the return of Christ?
