Matthew Henry on 2 Chronicles 33:1-10
We have here an account of the great wickedness of Manasseh. It is the same almost word for word with that which we had Kg2 21:1-9, and took a melancholy view of. It is no such pleasing subject that we should delight to dwell upon it again. This foolish young prince, in contradiction to the good example and good education his father gave him, abandoned himself to all impiety, transcribed the abominations of the heathen (Ch2 33:2), ruined the established religion, unravelled his father's glorious reformation (Ch2 33:3), profaned the house of God with his idolatry (Ch2 33:4, Ch2 33:5), dedicated his children to Moloch, and made the devil's lying oracles his guides and his counsellors, Ch2 33:6…

John Gill on 2 Chronicles 33:1

Tyndale Open Study Notes on 2 Chronicles 33:1-20
Manasseh ruled fifty-five years (697–642 BC), longer than any other king in Judah. The years of his reign included a co-regency with his father, Hezekiah, from 697 to 686 BC. Such a long reign was usually a sign of blessing, even though Manasseh did what was evil in the Lord’s sight. So the Chronicler tells of his humiliation, repentance, and restoration of worship in Judah.
