In 12: 1 - 13:6 Judah and Jerusalem are vindicated
against the nations and made victorious by Yahweh's intervention; the city repents and mourns for someone martyred in a just cause (the historical allusion is
unknown); and Yahweh now removes all idolatry and prophecy (degenerate prophecy, prophecy of a mercenary and corrupt form), and
effects Jerusalem's spiritual cleansing in a divine fountain.
