1 Now Naaman, captain of the host of the king of Syria, was a great man with his master, and honourable, because by him the LORD had given deliverance unto Syria: he was also a mighty man in valour, but he was a leper. 2 And the Syrians had gone out by companies, and had brought away captive out of the land of Israel a little maid; and she waited on Naaman's wife. 3 And she said unto her mistress, Would God my lord were with the prophet that is in Samaria! for he would recover him of his leprosy. 4 And one went in, and told his lord, saying, Thus and thus said the maid that is of the land of Israel. 5 And the king of Syria said, Go to, go, and I will send a letter unto the king of Israel. And he departed, and took with him ten talents of silver, and six thousand pieces of gold, and ten changes of raiment. 6 And he brought the letter to the king of Israel, saying, Now when this letter is come unto thee, behold, I have therewith sent Naaman my servant to thee, that thou mayest recover him of his leprosy. 7 And it came to pass, when the king of Israel had read the letter, that he rent his clothes, and said, Am I God, to kill and to make alive, that this man doth send unto me to recover a man of his leprosy? wherefore consider, I pray you, and see how he seeketh a quarrel against me. 8 And it was so, when Elisha the man of God had heard that the king of Israel had rent his clothes, that he sent to the king, saying, Wherefore hast thou rent thy clothes? let him come now to me, and he shall know that there is a prophet in Israel. 9 So Naaman came with his horses and with his chariot, and stood at the door of the house of Elisha. 10 And Elisha sent a messenger unto him, saying, Go and wash in the Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean. 11 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 the LORD his God, and strike his hand over the place, and recover the leper. 12 Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage. 13 And his servants came near, and spake unto him, and said, My father, if the prophet had bid thee do some great thing, wouldest thou not have done it? how much rather then, when he saith to thee, Wash, and be clean? 14 Then went he down, and dipped himself seven times in Jordan, according to the saying of the man of God: and his flesh came again like unto the flesh of a little child, and he was clean. 15 And he returned to the man of God, he and all his company, and came, and stood before him: and he said, Behold, now I know that there is no God in all earth, but in Israel: now therefore, I pray thee, take a blessing of thy servant. 16 But he said, As the LORD liveth, before whom I stand, I will receive none. And he urged him to take it; but he refused. 17 And Naaman said, Shall there not then, I pray thee, be given to thy servant two mules' burden of earth? for thy servant will henceforth offer neither burnt offering nor sacrifice unto other gods, but unto the LORD. 18 In this thing the LORD pardon thy servant, that when my master goeth into the house of Rimmon to worship there, and he leaneth on my hand, and I bow myself in the house of Rimmon: when I bow down myself in the house of Rimmon, the LORD pardon thy servant in this thing. 19 And he said unto him, Go in peace. So he departed from him a little way. 20 But Gehazi, the servant of Elisha the man of God, said, Behold, my master hath spared Naaman this Syrian, in not receiving at his hands that which he brought: but, as the LORD liveth, I will run after him, and take somewhat of him. 21 So Gehazi followed after Naaman. And when Naaman saw him running after him, he lighted down from the chariot to meet him, and said, Is all well? 22 And he said, All is well. My master hath sent me, saying, Behold, even now there be come to me from mount Ephraim two young men of the sons of the prophets: give them, I pray thee, a talent of silver, and two changes of garments. 23 And Naaman said, Be content, take two talents. And he urged him, and bound two talents of silver in two bags, with two changes of garments, and laid them upon two of his servants; and they bare them before him. 24 And when he came to the tower, he took them from their hand, and bestowed them in the house: and he let the men go, and they departed. 25 But he went in, and stood before his master. And Elisha said unto him, Whence comest thou, Gehazi? And he said, Thy servant went no whither. 26 And he said unto him, Went not mine heart with thee, when the man turned again from his chariot to meet thee? Is it a time to receive money, and to receive garments, and oliveyards, and vineyards, and sheep, and oxen, and menservants, and maidservants? 27 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.
[AD 373] Ephrem the Syrian on 2 Kings 5:1
“Naaman, commander of the army of the king of Aram, was a great man and in high favor with his master because by him the Lord had given victory to Aram.” Some rely on these words to say that he was the one who had killed Ahab by striking him with an arrow shot by his own hand, when there was war between [Israel] and Aram. This favor was granted him by the Lord as a reward for killing the persecutor of the prophets and for enfeebling the power of Jezebel, [Ahab’s] wife, and for restraining her cruelty. And thanks to him the disciples of Elijah had relief too, those whom the fear of Ahab and Jezebel had forced to flee into the desert and take refuge in some caves. And they had returned to their abodes, as the Scripture mentions below. But all these theories are groundless, except for what they say about the persecution of the prophets, which is undoubtedly correct. It is true, nevertheless, what Obadiah says to Elijah: “Has it not been told my lord what I did when Jezebel killed the prophets of the Lord, how I hid a hundred of the Lord’s prophets fifty to a cave and provided them with bread and water?”

[AD 253] Origen of Alexandria on 2 Kings 5:8-12
But in addition, that we may accept the interpretation of the Jordan, that river that is so fresh and grants so much grace, it is useful to present both Naaman the Syrian, who was cleansed from leprosy, and the comments made about the rivers by the enemies of religion. It is written of Naaman, therefore: “He came with his horse and chariot and stood at the doors of the house of Elisha. And Elisha sent a messenger to him, saying, ‘Go and wash seven times in the Jordan, and your flesh will return to you, and you will be cleansed.’ ” Then Naaman becomes angry because he does not perceive that it is our Jordan, and not the prophet, that removes the uncleanness of those who are unclean because of leprosy and heals them. For the work of a prophet is to send one to that which heals.Since, therefore, Naaman does not understand the great mystery of the Jordan, he says, “Behold, I said that he will assuredly come out to me and will stand and call on the name of the Lord his God and will place his hand on the place and the leprosy will recover,” for placing the hand on leprosy and cleansing it was the work of my Lord Jesus alone. To the man who asked with faith, “If you will, you can make me clean, he not only said “I will, be made clean,” but in addition to the word that he spoke, he also touched him, and he was cleansed from leprosy.
Naaman, who is still in error and does not see how inferior the other rivers are to the Jordan for healing the suffering, praises the rivers of Damascus, Abana and Pharphar, saying, “Are not the Abana and the Pharphar, rivers of Damascus, better than all the waters of Israel? Shall I not go and wash in them and be cleansed?”

[AD 373] Ephrem the Syrian on 2 Kings 5:8-12
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.

[AD 373] Ephrem the Syrian on 2 Kings 5:14-16
After Naaman had been persuaded by the prophet and had washed seven times in the Jordan, he eventually acknowledged his error. He was astonished, and a deep bewilderment took him when he realized that he had been delivered from his filthiness. And he thanked God for his healing and testified that the Lord of the universe, in his profound care for him, had conceded him that extraordinary power by simply using water. He also proclaimed that his healing could not have derived from the water of the river but had been caused by Elisha’s command. That is why he offered royal presents, but the prophet did not accept them and was not persuaded by the donor, even though he had pressed him many times. For that magnificently and very clearly prefigured the mystery of the healing, which is freely granted to all nations of the earth by our Lord through the intercession of the apostles. And this had been promised in advance to those masters by the prophet Isaiah, when he said, “You were sold for nothing, and you shall be redeemed without money.”Since all diseases are a sort of bondage, the prophet necessarily fixed the healing at the seventh bath, in parallel with the fact that the Law, too, orders and promises freedom for the slave at the seventh year.

[AD 542] Caesarius of Arles on 2 Kings 5:14-16
Let us further see what blessed Elisha commanded Naaman the Syrian. “Go,” he says, “and wash seven times in the Jordan.” When Naaman heard that he was to wash seven times in the Jordan, he was indignant and did not want to comply, but accepting the advice of his friends, he consented to be washed and was cleansed. This signified that before Christ was crucified, the Gentiles did not believe in Christ when he spoke in his own person, but afterwards they devoutly came to the sacrament of baptism after the preaching of the apostles. For this reason Elisha told Naaman to wash seven times in the Jordan. See, brothers: Elisha sent Naaman to the river Jordan because Christ was to send the Gentiles to baptism. Moreover, the fact that Elisha did not touch Naaman himself or baptize him showed that Christ did not come to the Gentiles himself but through his apostles to whom he said, “Go, and baptize all nations in the name of the Father, and of the Son and of the Holy Spirit.” Notice further that Naaman, who prefigured the Gentiles, recovered his health in the same river that later Christ consecrated by his baptism. However, when Naaman heard that he was to wash seven times in the Jordan, he became angry and said, “Are not the waters of my region better, the rivers of Damascus, the Abana and the Pharphar, that I may wash in them and be made clean?” When he had said this, his servants advised him to agree to the counsel of the prophet. Carefully notice what this means, brothers.Holy Elisha, as we said, typified our Lord and Savior, while Naaman prefigured the Gentiles. The fact that Naaman believed he would recover his health as the result of his own rivers indicates that the human race presumed on its free will and its own merits; but without the grace of Christ their own merits cannot possess health, although they can have leprosy. For this reason if the human race had not followed the example of Naaman and listened to the advice of Elisha, with humility receiving the gift of baptism through the grace of Christ, they could not be freed from the leprosy of the original and actual sins. “Wash seven times,” he said, because of the sevenfold grace of the Holy Spirit, which reposed in Christ our Lord. Moreover, when our Lord was baptized in this river, the Holy Spirit came on him in the form of a dove. When Naaman descended into the river as a figure of baptism, “his flesh became like the flesh of a little child.” Notice, beloved brothers, that this likeness was perfected in the Christian people, for you know that all who are baptized are still called infants, whether they are old or young. Those who are born old through Adam and Eve are reborn as young people to death, the second one to life. The former produces children of wrath; the latter generates them again as vessels of mercy. The apostle says, “In Adam all die; in Christ all will be made to live.” Therefore, just as Naaman, although he was an old man, became like a boy by washing seven times, so the Gentiles, although old by reason of their former sins and covered with the many spots of iniquity as with leprosy, are renewed by the grace of baptism in such a way that no leprosy of either original or actual sin remains in them. Thus, following the example of Naaman, they are renewed like little children by salutary baptism, although they have always been bent down under the weight of sins.

A blessing: a present.
[AD 373] Ephrem the Syrian on 2 Kings 5:17
Naaman the Aramean asked for some dust from the promised land in order to cause the shame of Israel, as I think, so that they might be ashamed that a stranger believed that even the dust of their land was filled with God, while the Hebrews did not even believe that God dwells in the prophets.

[AD 1781] Richard Challoner on 2 Kings 5:19
Go in peace: What the prophet here allowed, was not an outward conformity to an idolatrous worship; but only a service which by his office he owed to his master: who on all public occasions leaned on him: so that his bowing down when his master bowed himself down was not in effect adoring the idols: nor was it so understood by the standers by, since he publicly professed himself a worshipper of the only true and living God, but it was no more than doing a civil office to the king his master, whose leaning upon him obliged him to bow at the same time that he bowed.
[AD 373] Ephrem the Syrian on 2 Kings 5:21-22
Gehazi was a covetous man to the bottom of his heart. He had pretended to reject his hidden greed but saw, through the betrayal of his mouth, what his soul was trying to hide.

[AD 373] Ephrem the Syrian on 2 Kings 5:25-27
After Gehazi had come back from his meeting with Naaman, he entered Elisha’s house, and [the prophet] asked him, according to custom, why he had moved away from him. “Where do you come from?” he said to Gehazi. He said this on purpose, so that the justice of the judgment passed on his sin might be evident. If Gehazi repented and swore, he would have been forgiven; but if he denied that he had secretly received money, the leprosy of Naaman would cover him conspicuously.
