Exodus 8:9

9.And Moses said unto Pharaoh. Commentators differ as to the meaning of this passage. They are too speculative who expound it, that this honor was granted to Pharaoh, that he should fix the time in which Moses was to pray. Again, there is a flatness in the exposition, that Pharaoh might glory because the frogs were to die. Those who expound it, that Pharaoh should be freed from the frogs, so that he might glory in safety, express part of the meaning, but not the whole. It rather appears to me that there is an implied antithesis between the perverse boasting, wherewith Pharaoh had exulted, and that pious glowing which he ought to seek for in the mercy of God; as if Moses had said, “Thus far you have exalted yourself improperly, trusting in your power, and afterwards when bewitched by the enchantments; now rather glory, because you have an intercessor and patron to plead for you to God.” For it was needful that the arrogance, which had so falsely elevated him, that he dared to contend with God, should be crushed, and that no hope should be left him, save in the mercy of God. But to “glory over” Moses, means that he should seek his glory in the advocacy of Moses, and should account it a very great happiness that he should deign to interpose for his reconciliation with God. For the particle על, (93) is often so taken. Yet Moses by no means wished to detract at all from the glory of God; but (as I have lately said) desiring to humble the pride of the haughty king, he told him that nothing would be better and more glorious for him than to have a good hope of pardon, when he had obtained as his advocate the servant of the living God, whom he so cordially hated. He only affirms that the frogs should “remain in the river;” as much as to say that they should be content with their ordinary habitation and bounds; for we know that frogs, although they sometimes jump out on the bank, still do not go far from the water, because they are nourished by humidity. Thus he hints that they were let loose by God’s command to cover the ground, and that it was still in His power, if He chose, that they should invade the fields and houses again in new multitudes; and that it must be ascribed to His blessing, if they kept themselves in the waters, and did not make incursions beyond their own boundaries.
