The religious reform of King Josiah was triggered off by the discovery of the law book in the temple. The book is believed to have been the Book of the Law, possibly the book of Deuteronomy. This discovery was made during the repairs that Josiah ordered to be made to the temple in Jerusalem. When the book was read to Josiah, he realized how far the people of Judah had strayed from the commands of God and was deeply moved. He then initiated a religious reform to turn the people back to God and to follow His commands as stated in the book.
