2 Kings 15:1-5

In the twenty and seventh year of Jeroboam king of Israel began Azariah son of Amaziah king of Judah to reign. Sixteen years old was he when he began to reign, and he reigned two and fifty years in Jerusalem. And his mother's name was Jecholiah of Jerusalem. And he did that which was right in the sight of the LORD, according to all that his father Amaziah had done; save that the high places were not removed: the people sacrificed and burnt incense still on the high places. And the LORD smote the king, so that he was a leper unto the day of his death, and dwelt in a several house. And Jotham the king's son was over the house, judging the people of the land.
