Ephrem the Syrian : Naaman was suffering from leprosy, and when he heard that a prophet who lived under the command of Jehoram, king of Israel, could cure him, he left and proceeded to the country of the healer and went to the house of Elisha, because he had learned that he was the prophet who could aid him in his distress and that he had to ask him to be healed. But Elisha did not go out to meet him or speak to him. He informed him through a messenger: If he wanted to be healed, he had to wash his body in the Jordan seven times. Now a question rises: Why did Elisha prevent Naaman from seeing him and did not allow him to come into his house? In the first place, because he had served Ben-hadad in his wars. In fact, the prophet knew that the king of Aram had killed many children of Israel, and how Naaman had destroyed their lands and how his hands were stained with innocent blood, for he was the commander of the army and had received full authority over the Arameans. In the second place, because he was stopped by the corruption of leprosy. Elisha knew that the Law prescribed that no leper could be approached or touched.Naaman, as a consequence, was enraged. Blaming and accusing Elisha, he left [saying] that he would have never thought to come to a prophet just in order to see him act mysteriously and that he certainly did not expect such words. He believed that his healing would be accomplished through a simple imposition of the hands. So he blamed Elisha and said, "Why did he not come out to meet a man of power who had come to his house? And why did he prevent me from seeing him, and why did he not judge me worthy of speaking to him? And why did he not heal me with the remedy he uses and which is easy and effortless for me? On the contrary, he sends me to the Jordan, as though that river may really purify me; but are not the rivers of my land, the Amana and the Pharpar, sufficient for such purification?" It is not surprising that he had such thoughts and rebelled, the man who had heard with his own ears and compared the words of the prophet. A man who had made his career in the army could not have access to the mystery hidden in that unusual healing. Therefore Naaman was sent to the Jordan as to the remedy capable to heal a human being. Indeed, sin is the leprosy of the soul, which is not perceived by the senses, but intelligence has the proof of it, and human nature must be delivered from this disease by Christ's power which is hidden in baptism. It was necessary that Naaman, in order to be purified from two diseases, that of the soul and that of the body, might represent in his own person the purification of all the nations through the bath of regeneration, whose beginning was in the river Jordan, the mother and originator of baptism. — ON THE SECOND BOOK OF KINGS 5:10-11
