2 Chronicles 25:1-3

Amaziah was twenty and five years old when he began to reign; and he reigned twenty and nine years in Jerusalem: and his mother’s name was Jehoaddan, of Jerusalem. And he did that which was right in the eyes of Jehovah, but not with a perfect heart. Now it came to pass, when the kingdom was established unto him, that he slew his servants that had killed the king his father.
