2 Kings 21:20

as his father Manasseh did We can see from the notice of Manasseh in 2 Chronicles 33:17 that his repentance did not undo all the evil he had brought into the nation. -The people did sacrifice still in the high places, yetunto the Lord their God only". And on Amon, his son, the reformation of the father seems to have had no effect. -An ill guise is easily taken up, it is not so easily left. After a common depravation of religion, it is hard to return unto the first purity: as when a garment is deeply soiled it cannot without many lavers recover the former cleanness" (Bp Hall).
