'Murderers' in the Bible
Meanwhile, Elisha was sitting in his house, along with the elders, when the king sent a man to kill him, but before the messenger arrived, Elisha told the elders, "Are you watching how this descendant of murderers has ordered my head be cut off? Look, when the messenger arrives, shut the door and hold it to shut them out! Don't you hear the sound of his master's feet right behind him?"
but he did not execute the children of the murderers, in keeping with what is written in the Book of the Law of Moses, as the LORD had commanded: "Fathers must not be put to death because of their children's sin; nor are children to die because of their fathers' sin, for each person is to be put to death for his own sin."
