2 Kings 14:2-6

2He was twenty-five years old when he began to reign; and he reigned twenty-nine years in Jerusalem; and his mother's name was Jehoaddan of Jerusalem.

3And he did what was right in the sight of Jehovah, yet not like David his father: he did according to all that Joash his father had done.

4Only, the high places were not removed: the people still sacrificed and burned incense on the high places.

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.
