2 Kings 5:1 - Joseph Benson’s Commentary on the Old and New Testaments

Naaman was a great man with his master In great power and favour with the king of Syria; and honourable Highly esteemed, both for his quality and success; because the Lord by him had given deliverance unto Syria He had been victorious in such battles as he had fought, which coming to pass through the permission or appointment of the Divine Providence, the sacred writer would have the Israelites to look upon it as the Lord's doing. Let Israel know, that, when the Syrians prevailed, it was from the Lord. He gave them success in their wars, even with Israel, and for Israel's chastisement. But he was a leper This did not exclude him from the society of men in that country, where the Jewish law was not in force. But it was a great blemish upon him, and also likely to prove deadly; there being no cure for this disease, a disease very common in Syria.
