'Leper' in the Bible

Now Naaman, captain of the host of the king of Syria, was a great man with his master, and honourable, because by him the LORD had given deliverance unto Syria: he was also a mighty man in valour, but he was a leper.

And he took the letter to the king of Israel, in which the king of Aram had said, See, I have sent my servant Naaman to you to be made well, for he is a leper.

But the king of Israel, after reading the letter, was greatly troubled and said, Am I God, to give death and life? why does this man send a leper to me to be made well? is it not clear that he is looking for a cause of war?

But Naaman was wroth, 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 strike his hand over the place, and recover the leper.

The leprosy therefore of Naaman shall cleave unto thee, and unto thy seed for ever. And he went out from his presence a leper as white as snow.

And the LORD smote the king, so that he was a leper unto the day of his death, and dwelt in a several house. And Jotham the king's son was over the house, judging the people of the land.
