2 Kings 21:17

Now the rest of the acts of Manasseh and all that he did,
&c.] Both good and bad, for he repented, and was humbled, and did many good things afterwards, though not recorded in this book:

and his sin that he sinned;
his idolatry:

are they not written in the book of the chronicles of the kings of
Judah?
in which were recorded the most memorable events of their reigns; and in the canonical book of Chronicles are many things concerning Manasseh, which are not written here; see ( 2 Chronicles 33:11-16 ) .
