'Leper' in the Bible

Now Naaman, captain of the host of the king of Syria, was a great man with his master, and honorable, because by him Jehovah had given victory unto Syria: he was also a mighty man of valor, but he was a leper.

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