5:17 Two mules burden of earth - So he seems to farm the money which he brought with him, to express how little value he now set upon it. Ten talents (above three thousand five hundred pounds) in silver, with six thousand pieces of gold, (beside ten changes of raiment) were a burden for several mules. Shall I not give this to thy servant, Gehazi, if thou thyself will accept of nothing? This seems a more probable interpretation than the common one, that he wanted to build an altar therewith. For what altar could be built of the earth which two mules could carry into Syria? Unless they were as large and as strong as Elephants.
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.
