2 Chronicles 17:6

And his heart was lifted up in the ways of the Lord, it was so full of faith and piety that it was exalted above the lowness and meanness of idolatry and willful transgressions. Moreover, he took away the high places, those consecrated to Baal, and groves, the wooden pillars devoted to Astarte, out of Judah. It seems that the people resorted to idolatry just as soon as any king became lax in his insistence upon the true worship alone.
