Jeff Asher discusses the historical background for the book of Zephaniah. The book was written during the reign of King Josiah. Most likely, during the first few years of his reign as Josiah was preparing himself for the great task of restoration in Israel (2 Kings 22-23; 2 Chronicles 34-35). It was a wicked time, but a great time of religious zeal for the remnant in Judah.
