Adam Clarke on 2 Kings 11:1

Athaliah - This woman was the daughter of Ahab, and grand-daughter of Omri, and wife of Joram king of Judah, and mother of Ahaziah.

Destroyed all the seed royal - All that she could lay her hands on whom Jehu had left; in order that she might get undisturbed possession of the kingdom.

How dreadful is the lust of reigning! it destroys all the charities of life; and turns fathers, mothers, brothers, and children, into the most ferocious savages! Who, that has it in his power, makes any conscience "To swim to sovereign rule through seas of blood?"

In what a dreadful state is that land that is exposed to political revolutions, and where the succession to the throne is not most positively settled by the clearest and most decisive law! Reader, beware of revolutions; there have been some useful ones, but they are in general the heaviest curse of God.
