'Leper' in the Bible

Now Naaman, commander of the army of the king of Aram (Syria), was considered a great man by his king, and was highly respected because through Naaman the Lord had given victory to Aram (Syria). He was also a man of courage, but he was a leper.

But Naaman was furious and went away and said, “Indeed! I thought ‘He would at least come out to [see] me and stand and call on the name of the Lord his God, and wave his hand over the place [of leprosy] and heal the leper.’

Therefore, the leprosy of Naaman shall cling to you and to your descendants forever.” So Gehazi departed from his presence, a leper as white as snow.

And the Lord struck (afflicted) the king, and he was a leper until the day of his death, and lived in a separate house. Jotham the king’s son was in charge of the household, judging the people of the land.
