'Leper' in the Bible

And there was also many a leper in Israel in the time of the Prophet Elisha, and yet not one of them was cleansed, but Naaman the Syrian was."

And it came about that while he was in one of the towns, there was a leper there: and when he saw Jesus he went down on his face in prayer to him, saying, Lord, if it is your pleasure, you have power to make me clean.
