The following commentary covers Chapters 11 and 12.
judged, with Judah's royal family, as connected with Ahab
In chapter 11, the
judgment of God falls upon the family  which had corrupted Israel, and
even Judah also. The daughter of the house of Ahab, the
usurper of the throne of Judah, Athaliah, is cut off
through the faithfulness of the high priest, whose wife
had preserved one of the offspring of David.
Nevertheless there is not
true zeal for Jehovah. The priests keep the money to
themselves, which they had agreed to use for repairing
the house of the Lord, until the king interposes to set
things in order.
 During the time
that Ahab, stirred up by Jezebel, as well as his family
and sons are the instruments of Israel's apostasy and
corruption God sends the testimony of Elijah and Elisha.
This is, in the main (after Solomon), the subject of the
two Books of Kings. The fall of the house of David,
brought on by its alliance with Israel, or by the example
of their kings, is related in the end of the book, where
we find also the connections of the Assyrians with the
people of God.
