2 Chronicles 34:31-35

Then the king stood in his place and made a covenant before the Lord to walk after the Lord, and to keep His commandments, His testimonies, and His statutes with all his heart and with all his soul, to perform the words of the covenant that are written in this book.

Furthermore, he made all who were present in Jerusalem and Benjamin stand with him. So the inhabitants of Jerusalem acted in accordance with the covenant of God, the God of their fathers.

Josiah removed all the abominations from all the lands belonging to the sons of Israel, and made all who were present in Israel serve the Lord their God. Throughout his lifetime they did not turn from following the Lord God of their fathers.
