2 Kings 5:15 - Joseph Benson’s Commentary on the Old and New Testaments

He returned to the man of God To give him thanks and a recompense for the great benefit which he had received. I know there is no God in all the earth but in Israel By this wonderful work I am fully convinced that the God of Israel is the only true God, and that other gods are impotent idols. A noble confession! but such as speaks the misery of the Gentile world; for the nations that had many gods, really had no God, but were without God in the world. He had formerly thought the gods of Syria gods indeed, but now experience had rectified his mistake, and he knew Israel's God was God alone, the sovereign Lord of all. Had he merely seen other lepers cleansed, perhaps it would not have convinced him; but the mercy of the cure affected him more than the miracle of it. Those are best able to speak of the power of divine grace, who have themselves experienced it. I pray thee take a blessing of thy servant A thankful acknowledgment, or token of gratitude. The Hebrews called every gift a blessing.
