'Leper' in the Bible

Uzziah the king was a leper to the day of his death, and lived in a separate house, being a leper; for he was cut off from the house of Yahweh: and Jotham his son was over the king's house, judging the people of the land.

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