2 Chronicles 25:3-4

Now it came about as soon as the kingdom was firmly in his grasp, that he killed his servants who had slain his father the king. However, he did not put their children to death, but did as it is written in the law in the book of Moses, which the LORD commanded, saying, “Fathers shall not be put to death for sons, nor sons be put to death for fathers, but each shall be put to death for his own sin.”
