Incredibly, the women in these books are worse than the men.
Take Athaliah, Ahaziah's mother, who, on hearing her son is dead, sets about killing all his remaining family members and declares herself queen. Her sister, Jehosheba, manages to spirit Ahaziah's son Joash into a bedchamber and hide him from his murderous grandmother for six years.
In the seventh year of Athaliah's reign, the priest Jehoiada brings together all the spiritual and military leaders in the temple and makes a covenant with them, then shows them Joash. He instructs the soldiers to divide into three groups and watch all the entrances to the house. Anyone who approaches with weapons is to be killed. Then they crown the boy. Their clapping attracts Athaliah's attention. She comes into the temple, sees the boy in a crown, and cries out Treason, Treason (v. 14) Jehoaida orders her taken out by the horses' entrance and run through with a sword.
Then they go again to the temple of Baal and tear it down again and kill the priest again. Then they take the boy to the palace and kill his grandmother again for good measure.
