Here is, I. The invasion of the land by the locusts - God's great army, Joe 2:11. God bids Moses stretch out his hand (Exo 10:12), to beckon them, as it wee (for they came at a call), and he stretched forth his rod, Exo 10:13. Compare Exo 9:22 23. Moses ascribes it to the stretching out, not of his own hand, but the rod of God, the instituted sign of God's presence with him. The locusts obey the summons, and fly upon the wings of the wind, the east wind, and caterpillars without number, as we are told, Psa 105:34, Psa 105:35. A formidable army of horse and foot might more easily have been resisted than this host of insects. Who then is able to stand before the great God?

II.The desolations they made in it (Exo 10:15): They covered the face of the earth, and ate up the fruit of it. The earth God has given to the children of men; yet, when God pleases, he can disturb their possession and send locusts and caterpillars to force them out. Herbs grow for the service of man; yet, when God pleases, those contemptible insects shall not only be fellow-commoners with him, but shall plunder him, and eat the bread out of his mouth. Let our labour be, not for the habitation and meat which thus lie exposed, but for those which endure to eternal life, which cannot be thus invaded, nor thus corrupted.

III.Pharaoh's admission, hereupon, Exo 10:16, Exo 10:17. He had driven Moses and Aaron from him (Exo 10:11), telling them (it is likely) he would have no more to do with them. But now he calls for them again in all haste, and makes court to them with as much respect as before he had dismissed them with disdain. Note, The day will come when those who set at nought their counsellors, and despise all their reproofs, will be glad to make an interest in them and engage them to intercede on their behalf. The foolish virgins court the wise to give them of their oil; and see Psa 141:6. 1. Pharaoh confesses his fault: I have sinned against the Lord your God, and against you. He now sees his own folly in the slights and affronts he had put on God and his ambassadors, and seems at least, to repent of it. When God convinces men of sin, and humbles them for it, their contempt of God's ministers, and the word of the Lord in their mouths, will certainly come into the account, and lie heavily upon their consciences. Some think that when Pharaoh said, "The Lord your God," he did in effect say, "The Lord shall not be my God." Many treat with God as a potent enemy, whom they are willing not to be at war with, but care not for treating with him as their rightful prince, to whom they are willing to submit with loyal affection. True penitents lament sin as committed against God, even their own God, to whom they stand obliged. 2. He begs pardon, not of God, as penitents ought, but of Moses, which was more excusable in him, because, by a special commission, Moses was made a god to Pharaoh, and whosesoever sins he remitted they were forgiven; when he prays, Forgive this once, he, in effect, promises not to offend in like manner any more, yet seems loth to express that promise, nor does he say any thing particularly of letting the people go. Note, Counterfeit repentance commonly cheats men with general promises and is loth to covenant against particular sins. 3. He entreats Moses and Aaron to pray for him. There are those who, in distress, implore the help of other persons' prayers, but have no mind to pray for themselves, showing thereby that they have no true love to God, nor any delight in communion with him. Pharaoh desires their prayers that this death only might be taken away, not this sin: he deprecates the plague of locusts, not the plague of a hard heart, which yet was much the more dangerous.

IV.The removal of the judgment, upon the prayer of Moses, Exo 10:18, Exo 10:19. This was, 1. As great an instance of the power of God as the judgment itself. An east wind brought the locusts, and now a west wind carried them off. Note, Whatever point of the compass the wind is in, it is fulfilling God's word, and turns about by his counsel. The wind bloweth where it listeth, as it respects any control of ours; not so as it respects the control of God: he directeth it under the whole heaven. 2. It was as great a proof of the authority of Moses, and as firm a ratification of his commission and his interest in that God who both makes peace and creates evil, Isa 45:7. Nay, hereby he not only commanded the respect, but recommended himself to the good affections of the Egyptians, inasmuch as, while the judgment came in obedience to his summons, the removal of it was in answer to his prayers. He never desired the woeful day, though he threatened it. His commission indeed ran against Egypt, but his intercession was for it, which was a good reason why they should love him, though they feared him. 3. It was also as strong an argument for their repentance as the judgment itself; for by this it appeared that God is ready to forgive, and swift to show mercy. If he turn away a particular judgment, as he did often from Pharaoh, or defer it, as in Ahab's case, upon the profession of repentance and the outward tokens of humiliation, what will he do if we be sincere, and how welcome will true penitents be to him! O that this goodness of God might lead us to repentance!

V.Pharaoh's return to his impious resolution again not to let the people go (Exo 10:20), through the righteous hand of God upon him, hardening his heart, and confirming him in his obstinacy. Note, Those that have often baffled their convictions, and stood it out against them, forfeit the benefit of them, and are justly given up to those lusts of their own hearts which (how strong soever their convictions) prove too strong for them.

A mighty strong west wind - רוח ים ruach yam, literally the wind of the sea; the wind that blew from the Mediterranean Sea, which lay north-west of Egypt, which had the Red Sea on the east. Here again God works by natural means; he brought the locusts by the east wind, and took them away by the west or north-west wind, which carried them to the Red Sea where they were drowned.

The Red Sea - ים סוף yam suph, the weedy sea; so called, as some suppose, from the great quantity of alga or sea-weed which grows in it and about its shores. But Mr. Bruce, who has sailed the whole extent of it, declares that he never saw in it a weed of any kind; and supposes it has its name suph from the vast quantity of coral which grows in it, as trees and plants do on land. "One of these," he observes, "from a root nearly central, threw out ramifications in a nearly circular form measuring twenty-six feet diameter every way." - Travels, vol. ii., p. 138. In the Septuagint it is called θαλασσα ερυθρα, the Red Sea, from which version we have borrowed the name; and Mr. Bruce supposes that it had this name from Edom or Esau, whose territories extended to its coasts; for it is well known that the word אדם Edom in Hebrew signifies red or ruddy. The Red Sea, called also the Arabic Gulf, separates Arabia from Upper Ethiopia and part of Egypt. It is computed to be three hundred and fifty leagues in length from Suez to the Straits of Babelmandel, and is about forty leagues in breadth. It is not very tempestuous, and the winds usually blow from north to south, and from south to north, six months in the year; and, like the monsoons of India, invariably determine the seasons of sailing into or out of this sea. It is divided into two gulfs: that to the east called the Elanitic Gulf, from the city of Elana to the north end of it; and that to the west called the Heroopolitan Gulf, from the city of Heroopolis; the former of which belongs to Arabia, the latter to Egypt. The Heroopolitan Gulf is called by the Arabians Bahr el Kolzum, the sea of destruction, or of Clysmae, an ancient town in that quarter; and the Elanitic Gulf Bahr el Akaba, the sea of Akaba, a town situated on its most inland point.

And the Lord said unto Moses,.... About the eleventh day of the month Abib:

stretch out thine hand toward heaven; where the luminaries are, and from whence light comes:

that there may be darkness over the land of Egypt, even darkness which may be felt; that is, what caused it, the gross vapours and thick fogs; for otherwise darkness itself, being a privation of light, cannot be felt: Onkelos paraphrases it,"after that the darkness of the night is removed;''so Jonathan; that it might appear to be different from that, and be much grosser.

the Lord brought an east wind--The rod of Moses was again raised, and the locusts came. They are natives of the desert and are only brought by an east wind into Egypt, where they sometimes come in sun-obscuring clouds, destroying in a few days every green blade in the track they traverse. Man, with all his contrivances, can do nothing to protect himself from the overwhelming invasion. Egypt has often suffered from locusts. But the plague that followed the wave of the miraculous rod was altogether unexampled. Pharaoh, fearing irretrievable ruin to his country, sent in haste for Moses, and confessing his sin, implored the intercession of Moses, who entreated the Lord, and a "mighty strong west wind took away the locusts."
