2 Kings 11 & 12

In 2 Kings Chapters 11 & 12, King Ahaziah's mother decides she wants to rule over Judah after her son's death and starts killing off the rest of the royal family to secure her place on the throne. Ahaziah's sister steals away his infant son, Joash, and hides him in safety so he doesn't end up murdered. After 7 years, the priest fashions a coronation secretly and the crazy mom who stole the throne for the last 7 years is killed. So a 7 year old is now ruling over Judah, but not without the help of the priest.
