2 Kings 15:5-7

And Jehovah smote the king, so that he was a leper unto the day of his death, and dwelt in a separate house. And Jotham the king’s son was over the household, judging the people of the land. Now the rest of the acts of Azariah, and all that he did, are they not written in the book of the chronicles of the kings of Judah? And Azariah slept with his fathers; and they buried him with his fathers in the city of David: and Jotham his son reigned in his stead.
