15 Then he went back to the man of God, with all his train, and, taking his place before him, said, Now I am certain that there is no God in all the earth, but only in Israel: now then, take an offering from me. 16 But he said, By the life of the Lord whose servant I am, I will take nothing from you. And he did his best to make him take it but he would not. 17 Then Naaman said, If you will not, then let there be given to your servant as much earth as two beasts are able to take on their backs; because from now on, your servant will make no offering or burned offering to other gods, but only to the Lord. 18 But may your servant have the Lord's forgiveness for this one thing: when my master goes into the house of Rimmon for worship there, supported on my arm, and my head is bent in the house of Rimmon; when his head is bent in the house of Rimmon, may your servant have the Lord's forgiveness for this thing. 19 And he said to him, Go in peace. And he went from him some distance.

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.
