Josiah or Yoshiyahu was king of Judah, and son of Amon and Jedidah, the daughter of Adaiah of Bozkath. His grandfather was King Manasseh, who had turned from the Jewish religion, even adapting the Temple for worship that was considered idolatrous by faithful Jews. Josiah is credited by some historians with having established Jewish scripture in written form as a part of the Deuteronomic reform that occurred during his rule.
