John Gill Commentary 2 Chronicles 34:33

"And Josiah took away all the abominations out of all the countries that pertained to the children of Israel, and made all that were found in Israel to serve, even to serve Jehovah their God. All his days they departed not from following Jehovah, the God of their fathers." — 2 Chronicles 34:33 (ASV)

And Josiah took away all the abominations out of all the
countries that [pertained] to the children of Israel
All their idols, as related in (2 Kings 23:4)

and made all that were present in Israel to serve, even to serve the
Lord their God ;
by his edicts, and by his example:

and all his days they departed not from following the Lord God of their
fathers ;
not publicly and universally; otherwise there were great declensions and corruptions among them, as the prophecies of Jeremiah and Zephaniah show.
