19 "Go in peace," Elisha said. So Naaman started home again.

20 But Gehazi, the servant of Elisha, the man of God, said to himself, "My master should not have let this Aramean get away without accepting any of his gifts. As surely as the Lord lives, I will chase after him and get something from him." 21 So Gehazi set off after Naaman. When Naaman saw Gehazi running after him, he climbed down from his chariot and went to meet him. "Is everything all right?" Naaman asked. 22 "Yes," Gehazi said, "but my master has sent me to tell you that two young prophets from the hill country of Ephraim have just arrived. He would like 75 pounds of silver and two sets of clothing to give to them." 23 "By all means, take twice as much silver," Naaman insisted. He gave him two sets of clothing, tied up the money in two bags, and sent two of his servants to carry the gifts for Gehazi. 24 But when they arrived at the citadel, Gehazi took the gifts from the servants and sent the men back. Then he went and hid the gifts inside the house. 25 When he went in to his master, Elisha asked him, "Where have you been, Gehazi?" "I haven't been anywhere," he replied.

Commentary on 2 Kings 5:15-19

(Read 2 Kings 5:15-19)

The mercy of the cure affected Naaman more than the miracle. Those are best able to speak of the power of Divine grace, who themselves experience it. He also shows himself grateful to Elisha the prophet. Elijah refused any recompence, not because he thought it unlawful, for he received presents from others, but to show this new convert that the servants of the God of Israel looked upon worldly wealth with a holy contempt. The whole work was from God, in such a manner, that the prophet would not give counsel when he had no directions from the Lord. It is not well violently to oppose the lesser mistakes which unite with men's first convictions; we cannot bring men forward any faster than the Lord prepares them to receive instruction. Yet as to us, if, in covenanting with God, we desire to reserve any known sin, to continue to indulge ourselves in it, that is a breach of his covenant. Those who truly hate evil, will make conscience of abstaining from all appearances of evil.

Commentary on 2 Kings 5:20-27

(Read 2 Kings 5:20-27)

Naaman, a Syrian, a courtier, a soldier, had many servants, and we read how wise and good they were. Elisha, a holy prophet, a man of God, has but one servant, and he proves a base liar. The love of money, that root of all evil, was at the bottom of Gehazi's sin. He thought to impose upon the prophet, but soon found that the Spirit of prophecy could not be deceived, and that it was in vain to lie to the Holy Ghost. It is folly to presume upon sin, in hopes of secrecy. When thou goest aside into any by-path, does not thy own conscience go with thee? Does not the eye of God go with thee? He that covers his sin, shall not prosper; particularly, a lying tongue is but for a moment. All the foolish hopes and contrivances of carnal worldlings are open before God. It is not a time to increase our wealth, when we can only do it in such ways as are dishonourable to God and religion, or injurious to others. Gehazi was punished. If he will have Naaman's money, he shall have his disease with it. What was Gehazi profited, though he gained two talents, when thereby he lost his health, his honour, his peace, his service, and, if repentance prevented not, his soul for ever? Let us beware of hypocrisy and covetousness, and dread the curse of spiritual leprosy remaining on our souls.
