2 Kings 14:5-6

5And it came to pass when the kingdom was established in his hand, that he slew his servants who had smitten the king his father.

6But the children of those that smote [him] he did not put to death; according to that which is written in the book of the law of Moses, wherein Jehovah commanded saying, The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers; but every man shall be put to death for his own sin.
