But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the LORD 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 be put to death for his own sin.
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 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."
However, he did not kill the children of the assassins, for he obeyed the command of the LORD as written by Moses in the Book of the Law: “Parents must not be put to death for the sins of their children, nor children for the sins of their parents. Those deserving to die must be put to death for their own crimes.”
