Who began his ministry in Judah at a time when Judah was being purged and cleansed of idolatry and apostasy?

The prophet Jeremiah began his ministry in Judah during a period of significant religious reform and a push to eliminate idolatry and apostasy. His prophetic work coincided with the reign of King Josiah, who initiated extensive reforms aimed at restoring the worship of Yahweh and removing pagan practices. Jeremiah's messages often called for genuine repentance and adherence to God's covenant amid these turbulent times.
