Matthew Henry on 2 Chronicles 33:11-20
We have seen Manasseh by his wickedness undoing the good that his father had done; here we have him by repentance undoing the evil that he himself had done. It is strange that this was not so much as mentioned in the book of Kings, nor does any thing appear there to the contrary but that he persisted and perished in his son. But perhaps the reason was because the design of that history was to show the wickedness of the nation which brought destruction upon them; and this repentance of Manasseh and the benefit of it, being personal only and not national, is overlooked there; yet here it is fully related, and a memorable instance it is of the riches of God's pardoning mercy and the power of hi…

In Ch2 33:16, instead of the Keth. ויבן, he built (restored) the altar of Jahve, many manuscripts and ancient editions read ויכן, he prepared the altar of Jahve. This variation has perhaps originated in an orthographical error, and it is difficult to decide which reading is the original. The Vulg. translates יבן restauravit.
