John Wesley on Jeremiah 31:22

Backsliding - Running after idols; or seeking help from foreign nations, instead of applying to God. A woman - This seems to be a promise of the Jewish church in its time, and of the gospel - church, prevailing over all its enemies; though, considering the fewness of the church's members, with the multitude of its enemies, and their power, it seemed as strange a thing, as for a woman to prevail against a strong and mighty man.
