Exodus 10:12

12.And the Lord said unto Moses. Since Pharaoh was not induced to obey by the announcement of the punishment, its execution is here related. And first, Moses is commanded to stretch out his hand to bring in the locusts, in right of the authority with which God had invested him; for the stretching forth of the hand is a token of power. He therefore adds, just beyond, that he stretched forth his rod, which we have before seen to have been given him as a royal scepter. It is, then, just as if God had appointed him to be His vicegerent, and had subjected to him the sea, and earth, and air. But that he may sink down into the character of a minister, he does not say that the locusts came up at his command, but assigns the glory of the operation to the Lord alone. And this mode of expression is worthy of remark, since we learn from it that the ministers of God, although they bring nothing of their own, still do not lose their labor, because the efficacy of the Spirit is conjoined to their word; and still that nothing is detracted from the power of God and transferred to them, since they are but instruments, which by God’s hand are applied in His service. Thus did not Moses in vain command, as he stretched forth his rod, the locusts to come up; because the effect of his command immediately appeared. Still he did not himself create the locusts, nor attract them by the stirring’ of his rod, but they were divinely brought by the power of the east wind. But so sudden a gathering unquestionably occurred contrary to the order of nature; nor, if God thus employed the wind, does it necessarily follow that this was usual. We know that the east wind is a wholesome and gentle wind, and although it is sometimes stormy with respect to Judea, still it does not seem probable that either by its strength or by its contagious blast, Egypt was covered with locusts. But it is possible that God, bringing in the immense abundance of locusts by a sudden whirlwind, gave the Egyptians a sign of their approaching calamity, so that it might be more manifest that they had not arisen otherwise than in accordance with the prediction of Moses. That “before them there were no such locusts as they, neither after them shall be such,” is no contradiction to the declaration of Joel, who also affirms that such an instance had never occurred, as that the locust should eat what the palmer-worm had left; and what the locust had left the canker-worm should eat; and what the canker-worm had left the caterpillar should eat., (Joel 1:4;) for he is not there speaking of a single punishment, but of its varied and multiform continuation.
