Still today the European nations are known by the names of women such as Europa, Britannia, Germania etc. This is because Israel was the bride of Christ.
The wife vows to obey the husband and the husband vows to care for and love the wife, this was the exact relationship laid out in the covenants between God and Israel.
Once the vows were broken, there was no choice but for God to divorce them, but the Abrahamic covenant still stood and they were told they would be reconciled to God at some point in the future, which they were through Christ.
