“As soon as the royal power was firmly in his hand, King Amaziah killed his servants who had slaughtered his father King Joash. But 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 Yahweh commanded. ‘The parents shall not be put to death for the children, or the children be put to death for the parents. All shall be put to death for their own sin.’”
One of the first acts of King Amaziah was to avenge the death of his father. For some unexplained reasons, the servants had killed his father. Now he in turn has killed them. However, there is the important remark about not killing their children. Many of the kings tried to wipe out entire families by killing their children so that there would be no heir. Here there is a strong reminder of the Mosaic Law that only the sinner, no one in his family, should be put to death. This is based on the explicit and exact saying from Deuteronomy, chapter 24, about individual responsibility. This is a further indication that this biblical author may have the same as Deuteronomy.
