2 Kings 23 (KJV)

3 And the king stood by a pillar, and made a covenant before the Lord, to walk after the Lord, and to keep his commandments and his testimonies and his statutes with all their heart and all their soul, to perform the words of this covenant that were written in this book. And all the people stood to the covenant.

24 Moreover the workers with familiar spirits, and the wizards, and the images, and the idols, and all the abominations that were spied in the land of Judah and in Jerusalem, did Josiah put away, that he might perform the words of the law which were written in the book that Hilkiah the priest found in the house of the Lord.
25 And like unto him was there no king before him, that turned to the Lord with all his heart, and with all his soul, and with all his might, according to all the law of Moses; neither after him arose there any like him.
