King Yohoyochim, "the Jewish Caligula," was not just an idolater, he was responsible for the torture of the prophet Jeremiah. His son and successor Yohoyochin began his reign with a cruelty equaling his father's, but in a dramatic turn of events, he accepted Jeremiah's prophecy and returned to the ways of Hashem. With vivid illustrations from Tanach and Medrash, Rabbi Wein captures the spirit of the tumultuous years before the exile and delivers a powerful message about teshuva.
