'Leper' in the Bible

Now Naaman, captain of the army of the king of Syria, was a great man with his master, and honorable, because by him Yahweh had given victory to Syria: he was also a mighty man of valor, [but he was] a leper.

But Naaman was angry, and went away, and said, "Behold, I thought, 'He will surely come out to me, and stand, and call on the name of Yahweh his God, and wave his hand over the place, and heal the leper.'

Therefore the leprosy of Naaman will cling to you and to your seed forever." He went out from his presence a leper, as white as snow.

Yahweh struck the king, so that he was a leper to the day of his death, and lived in a separate house. Jotham the king's son was over the household, judging the people of the land.
