The threatened plague of hail is here summoned by the powerful hand and rod of Moses (Exo 9:22, Exo 9:23), and it obeys the summons, or rather the divine command; for fire and hail fulfil God's word, Psa 148:8. And here we are told,

I.What desolations it made upon the earth. The thunder, and fire from heaven (or lightning), made it both the more dreadful and the more destroying, Exo 9:23, Exo 9:24. Note, God makes the clouds, not only his store-houses whence he drops fatness on his people, but his magazines whence, when he pleases, he can draw out a most formidable train of artillery, with which to destroy his enemies. He himself speaks of the treasures of hail which he hath reserved against the day of battle and war, Job 38:22, Job 38:23. Woeful havoc this hail made in the land of Egypt. It killed both men and cattle, and battered down, not only the herbs, but the trees, Exo 9:25. The corn that was above ground was destroyed, and that only preserved which as yet had not come up, Exo 9:31, Exo 9:32. Note, God has many ways of taking away the corn in the season thereof (Hos 2:9), either by a secret blasting, or a noisy hail. In this plague the hot thunderbolts, as well as the hail, are said to destroy their flocks, Psa 78:47, Psa 78:48; and see Psa 105:32, Psa 105:33. Perhaps David alludes to this when, describing God's glorious appearances for the discomfiture of his enemies, he speaks of the hailstones and coals of fire he threw among them, Psa 18:12, Psa 18:13. And there is a plan reference to it on the pouring out of the seventh vial, Rev 16:21. Notice is here taken (Exo 9:26) of the land of Goshen's being preserved from receiving any damage by this plague. God has the directing of the pregnant clouds, and causes it to rain or hail on one city and not on another, either in mercy or in judgment.

II.What a consternation it put Pharaoh in. See what effect it had upon him, 1. He humbled himself to Moses in the language of a penitent, Exo 9:27, Exo 9:28. No man could have spoken better. He owns himself on the wrong side in his contest with the God of the Hebrews: "I have sinned in standing it out so long." He owns the equity of God's proceedings against him: The Lord is righteous, and must be justified when he speaks, though he speak in thunder and lightning. He condemns himself and his land: "I and my people are wicked, and deserve what is brought upon us." He begs the prayers of Moses: "Entreat the Lord for me, that this direful plague may be removed." And, lastly, he promises to yield up his prisoners: I will let you go. What could one desire more? And yet his heart was hardened all this while. Note, The terror of the rod often extorts penitent acknowledgments from those who have no penitent affections; under the surprise and smart of affliction, they start up, and say that which is pertinent enough, not because they are deeply affected, but because they know that they should be and that it is meet to be said. 2. Moses, hereupon, becomes an intercessor for him with God. Though he had all the reason in the world to think that he would immediately repent of his repentance, and told him so (Exo 9:30), yet he promises to be this friend in the court of heaven. Note, Even those whom we have little hopes of, yet we should continue to pray for, and to admonish, Sa1 12:23. Observe, (1.) The place Moses chose for his intercession. He went out of the city (Exo 9:33), not only for privacy in his communion with God, but to show that he durst venture abroad into the field, notwithstanding the hail and lightning which kept Pharaoh and his servants within doors, knowing that every hail-stone had its direction from his God, who meant him no hurt. Note, Peace with God makes men thunderproof, for thunder is the voice of their Father. (2.) The gesture: He spread abroad his hands unto the Lord - an outward expression of earnest desire and humble expectation. Those that come to God for mercy must stand ready to receive it. (3.) The end Moses aimed at in interceding for him: That thou mayest know, and be convinced, that the earth is the Lord's (Exo 9:29), that is, that God has a sovereign dominion over all the creatures, that they all are ruled by him, and therefore that thou oughtest to be so. See what various methods God uses to bring men to their proper senses. Judgments are sent, judgments removed, and all for the same end, to make men know that he Lord reigns. (4.) The success of it. [1.] He prevailed with God, Exo 9:33. But, [2.] He could not prevail with Pharaoh: He sinned yet more, and hardened his heart, Exo 9:34, Exo 9:35. The prayer of Moses opened and shut heaven, like Elias's (Jam 5:17, Jam 5:18), and such is the power of God's two witnesses (Rev 11:6); yet neither Moses nor Elias, nor those two witnesses, could subdue the hard hearts of men. Pharaoh was frightened into a compliance by the judgment, but, when it was over, his convictions vanished, and his fair promises were forgotten. Note, Little credit is to be given to confessions upon the rack. Note also, Those that are not bettered by judgments and mercies are commonly made worse.

And the heart of Pharaoh was hardened - In consequence of his sinning yet more, and hardening his own heart against both the judgments and mercies of God, we need not be surprised that, after God had given him the means of softening and repentance, and he had in every instance resisted and abused them, he should at last have been left to the hardness and darkness of his own obstinate heart, so as to fill up the measure of his iniquity, and rush headlong to his own destruction.

In the fifth, sixth, and seventh plagues described in this chapter, we have additional proofs of the justice and mercy of God, as well as of the stupidity, rebellion, and wickedness of Pharaoh and his courtiers. As these continued to contradict and resist, it was just that God should continue to inflict those punishments which their iniquities deserved. Yet in the midst of judgment he remembers mercy; and therefore Moses and Aaron are sent to inform the Egyptians that such plagues would come if they continued obstinate. Here is mercy; the cattle only are destroyed, and the people saved! Is it not evident from all these messages, and the repeated expostulations of Moses and Aaron in the name and on the authority of God, that Pharaoh was bound by no fatal necessity to continue his obstinacy; that he might have humbled himself before God, and thus prevented the disasters that fell on the land, and saved himself and his people from destruction? But he would sin, and therefore he must be punished.

In the sixth plague Pharaoh had advantages which he had not before. The magicians, by their successful imitations of the miracles wrought by Moses, made it doubtful to the Egyptians whether Moses himself was not a magician acting without any Divine authority; but the plague of the boils, which they could not imitate, by which they were themselves afflicted, and which they confessed to be the finger of God, decided the business.

Pharaoh had no longer any excuse, and must know that he had now to contend, not with Moses and Aaron, mortals like himself, but with the living God. How strange, then, that he should continue to resist! Many affect to be astonished at this, and think it must be attributed only to a sovereign controlling influence of God, which rendered it impossible for him to repent or take warning. But the whole conduct of God shows the improbability of this opinion: and is not the conduct of Pharaoh and his courtiers copied and reacted by thousands who are never suspected to be under any such necessitating decree? Every sinner under heaven, who has the Bible in his hand, is acting the same part. God says to the swearer and the profane, Thou shalt not take the name of the Lord thy God in vain; and yet common swearing and profaneness are most scandalously common among multitudes who bear the Christian name, and who presume on the mercy of God to get at last to the kingdom of heaven! He says also, Remember the Sabbath day to keep it holy; thou shalt not kill; thou shalt not commit adultery; thou shalt not steal; thou shalt not bear false witness; thou shalt not covet; and sanctions all these commandments with the most awful penalties: and yet, with all these things before them, and the professed belief that they came from God, Sabbath-breakers, men-slayers, adulterers, fornicators, thieves, dishonest men, false witnesses, liars, slanderers, backbiters, covetous men, lovers of the world more than lovers of God, are found by hundreds and thousands! What were the crimes of the poor half-blind Egyptian king when compared with these! He sinned against a comparatively unknown God; these sin against the God of their fathers - against the God and Father of Him whom they call their Lord and Savior, Jesus Christ! They sin with the Bible in their hand, and a conviction of its Divine authority in their hearts. They sin against light and knowledge; against the checks of their consciences, the reproofs of their friends, the admonitions of the messengers of God; against Moses and Aaron in the law; against the testimony of all the prophets; against the evangelists, the apostles, the Maker of heaven and earth, the Judge of all men, and the Savior of the world! What were Pharaoh's crimes to the crimes of these? On comparison, his atom of moral turpitude is lost in their world of iniquity. And yet who supposes these to be under any necessitating decree to sin on, and go to perdition? Nor are they; nor was Pharaoh. In all things God has proved both his justice and mercy to be clear in this point. Pharaoh, through a principle of covetousness, refused to dismiss the Israelites, whose services he found profitable to the state: these are absorbed in the love of the world, the love of pleasure, and the love of gain; nor will they let one lust go, even in the presence of the thunders of Sinai, or in sight of the agony, bloody sweat, crucifixion, and death of Jesus Christ! Alas! how many are in the habit of considering Pharaoh the worst of human beings, inevitably cut off from the possibility of being saved because of his iniquities, who outdo him so far in the viciousness of their lives, that Pharaoh, hardening his heart against ten plagues, appears a saint when compared with those who are hardening their hearts against ten millions of mercies. Reader, art thou of this number? Proceed no farther! God's judgments linger not. Desperate as thy state is, thou mayest return; and thou, even thou, find mercy through the blood of the Lamb.

See the observations at the conclusion of the next chapter. See Clarke at Exo 10:29 (note).

And the heart of Pharaoh was hardened,.... Instead of being softened, as it seemed to be when under the plague, it became harder and harder when delivered from it:

neither would he let the children of Israel go; though he had so absolutely promised it, and assured them that he would not keep them, and that they should not stay any longer:

as the Lord had spoken by Moses; that so his heart would be hardened until the signs and wonders were multiplied upon him, God designed to perform, Exo 4:21.

the flax and the barley was smitten, &c.--The peculiarities that are mentioned in these cereal products arise from the climate and physical constitution of Egypt. In that country flax and barley are almost ripe when wheat and rye (spelt) are green. And hence the flax must have been "bolled"--that is, risen in stalk or podded in February, thus fixing the particular month when the event took place. Barley ripens about a month earlier than wheat. Flax and barley are generally ripe in March, wheat and rye (properly, spelt) in April.
