2 Kings 14:5-7

5And it came to pass, as soon as the kingdom was established in his hand, that he slew his servants who had slain the king his father: 6but the children of the murderers he put not to death; according to that which is written in the book of the law of Moses, as Jehovah commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall die for his own sin. 7He slew of Edom in the Valley of Salt ten thousand, and took Sela by war, and called the name of it Joktheel, unto this day.
