2 Kings 15:5-7

5And Jehovah smote the king, so that he was a leper to the day of his death, and dwelt in a separate house. And Jotham the king's son was over the house, judging the people of the land.

6And 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?

7And 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.
