Adam Clarke's Bible Commentary Verse 7. He set a graven image of the grove that he had made in the house] Every one may see that Asherah here must signify an idol, and not a grove; and for the proof of this see the observations at the end of the chapter.
Matthew Henry Commentary
Verses 1-9 - Young persons generally desire to become their own masters, and to have early possession of riches and power. But this, for the most part ruins their future comfort, and causes mischief to others. It is muc happier when young persons are sheltered under the care of parents of guardians, till age gives experience and discretion. Though such youn persons are less indulged, they will afterwards be thankful. Manasse wrought much wickedness in the sight of the Lord, as if on purpose to provoke him to anger; he did more evil than the nations whom the Lor destroyed. Manasseh went on from bad to worse, till carried captive to Babylon. The people were ready to comply with his wishes, to obtain his favour and because it suited their depraved inclinations. In the reformation of large bodies, numbers are mere time-servers, and in temptation fall away.
