'Leper' in the Bible

Now Naaman, captain of the army of the king of Aram, was a great man with his master, and highly respected, because by him the Lord had given victory to Aram. The man was also a valiant warrior, but he was a leper.

But Naaman was furious and went away and said, “Behold, I thought, ‘He will surely come out to me and stand and call on the name of the Lord his God, and wave his hand over the place and cure the leper.’

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

The Lord struck the king, so that he was a leper to the day of his death. And he lived in a separate house, while Jotham the king’s son was over the household, judging the people of the land.
