2 Chronicles 34:30-33
34:30 The king went up to the Lord’s temple, accompanied by all the people of Judah, the residents of Jerusalem, the priests, and the Levites. All the people were there, from the oldest to the youngest. He read aloud all the words of the scroll of the covenant that had been discovered in the Lord’s temple.
34:31 The king stood by his pillar and renewed the covenant before the Lord, agreeing to follow the Lord and to obey his commandments, laws, and rules with all his heart and being, by carrying out the terms of this covenant recorded on this scroll.
34:32 He made all who were in Jerusalem and Benjamin agree to it. The residents of Jerusalem acted in accordance with the covenant of God, the God of their ancestors.
34:33 Josiah removed all the detestable idols from all the areas belonging to the Israelites and encouraged all who were in Israel to worship the Lord their God. Throughout the rest of his reign they did not turn aside from following the Lord God of their ancestors.
