2 Kings 14:5-7

5And as soon as the royal power was firmly in his hand, he struck down his servants who had struck down the king his father.

6But he did not put to death the children of the murderers, according to what is written in the Book of the Law of Moses, where the Lord commanded, "Fathers shall not be put to death because of their children, nor shall children be put to death because of their fathers. But each one shall die for his own sin."

7He struck down ten thousand Edomites in the Valley of Salt and took Sela by storm, and called it Joktheel, which is its name to this day.
