Naaman the Aramean was a commander of the armies of Hadadezer, the king of Aram-Damascus, in the time of Jehoram, King of Northern Israel.
According to 2 Kings 5 in the Bible, Naaman was a commander of the army of Aram. He was a good commander and was held in favor because of the victory that God brought him. However, Naaman suffered from tzaraath, a skin disease often translated as "leprosy". From Wikipedia
