2 Chronicles 26:21-23

21And King Uzziah was a leper to the day of his death, and being a leper lived in a separate house, for he was excluded from the house of the Lord. And Jotham his son was over the king's household, governing the people of the land.

22Now the rest of the acts of Uzziah, from first to last, Isaiah the prophet the son of Amoz wrote.

23And Uzziah slept with his fathers, and they buried him with his fathers in the burial field that belonged to the kings, for they said, "He is a leper." And Jotham his son reigned in his place.
