Here, I. Moses is instructed. We may well suppose that he, for his part, was much astonished both at Pharaoh's obstinacy and at God's severity, and could not but be compassionately concerned for the desolations of Egypt, and at a loss to conceive what this contest would come to at last. Now here God tells him what he designed, not only Israel's release, but the magnifying of his own name: That thou mayest tell in thy writings, which shall continue to the world's end, what I have wrought in Egypt, Exo 10:1, Exo 10:2. The ten plagues of Egypt must be inflicted, that they may be recorded for the generations to come as undeniable proofs, 1. Of God's overruling power in the kingdom of nature, his dominion over all the creatures, and his authority to use them either as servants to his justice or sufferers by it, according to the counsel of his will. 2. Of God's victorious power over the kingdom of Satan, to restrain the malice and chastise the insolence of his and his church's enemies. These plagues are standing monuments of the greatness of God, the happiness of the church, and the sinfulness of sin, and standing monitors to the children of men in all ages not to provoke the Lord to jealousy nor to strive with their Maker. The benefit of these instructions to the world sufficiently balances the expense.

II.Pharaoh is reproved (Exo 10:3): Thus saith the Lord God of the poor, despised, persecuted, Hebrews, How long wilt thou refuse to humble thyself before me? Note, It is justly expected from the greatest of men that they humble themselves before the great God, and it is at their peril if they refuse to do it. This has more than once been God's quarrel with princes. Belshazzar did not humble his heart, Dan 5:22. Zedekiah humbled not himself before Jeremiah, Ch2 36:12. Those that will not humble themselves God will humble. Pharaoh had sometimes pretended to humble himself, but no account was made of it, because he was neither sincere nor constant in it.

III.The plague of locusts is threatened, Exo 10:4-6. The hail had broken down the fruits of the earth, but these locusts should come and devour them: and not only so, but they should fill their houses, whereas the former inroads of these insects had been confined to their lands. This should be much worse than all the calamities of that king which had ever been known. Moses, when he had delivered his message, not expecting any better answer than he had formerly, turned himself and went out from Pharaoh, Exo 10:6. Thus Christ appointed his disciples to depart from those who would not receive them, and to shake off the dust of their feet for a testimony against them; and ruin is not far off from those who are thus justly abandoned by the Lord's messengers, Sa1 15:27, etc.

IV.Pharaoh's attendants, his ministers of state, or privy-counsellors, interpose, to persuade him to come to some terms with Moses, Exo 10:7. They, as in duty bound, represent to him the deplorable condition of the kingdom (Egypt is destroyed), and advise him by all means to release his prisoners (Let the men go); for Moses, they found, would be a snare to them till it was done, and it were better to consent at first than to be compelled at last. The Israelites had become a burdensome stone to the Egyptians, and now, at length, the princes of Egypt were willing to be rid of them, Zac 12:3. Note, It is a thing to be regretted (and prevented, if possible) that a whole nation should be ruined for the pride and obstinacy of its princes, Salus populi suprema lex - To consult the welfare of the people is the first of laws.

V.A new treaty is, hereupon, set on foot between Pharaoh and Moses, in which Pharaoh consents for the Israelites to go into the wilderness to do sacrifice; but the matter in dispute was who should go, Exo 10:8. 1. Moses insists that they should take their whole families, and all their effects, along with them, Exo 10:9. note, Those that serve God must serve him with all they have. Moses pleads, "We must hold a feast, therefore we must have our families to feast with, and our flocks and herds to feast upon, to the honour of God." 2. Pharaoh will by no means grant this: he will allow the men to go, pretending that this was all they desired, though this matter was never yet mentioned in any of the former treaties; but, for the little ones, he resolves to keep them as hostages, to oblige them to return, Exo 10:10, Exo 10:11. In a great passion he curses them, and threatens that, if they offer to remove their little ones, they will do it at their peril. Note, Satan does all he can to hinder those that serve God themselves from bringing their children in to serve him. He is a sworn enemy to early piety, knowing how destructive it is to the interests of his kingdom; whatever would hinder us from engaging our children to the utmost in God's service, we have reason to suspect the hand of Satan in it. 3. The treaty, hereupon, breaks off abruptly; those that before went out from Pharaoh's presence (Exo 10:6) were now driven out. Those will quickly hear their doom that cannot bear to hear their duty. See Ch2 25:16. Quos Deus destruet eos dementat - Whom God intends to destroy he delivers up to infatuation. Never was man so infatuated to his own ruin as Pharaoh was.

They shall cover the face of the earth - They sometimes cover the whole ground to the depth of six or eight inches. See the preceding accounts.

And they shall cover the face of the earth, that one cannot be able to see the earth,.... Or, "cover the eye of the earth" (z); either the appearance and colour of the earth, so as they could not be discerned for the multitude of the locusts on it; so the word is used in Num 11:7 or the eye of man looking upon the earth, which would not be able to see it, because the locusts would be between his eye and the earth. The Targum of Onkelos is,"and shall cover the eye of the sun of the earth,''so that its rays shall not reach the earth; and so Abarbinel interprets it of the sun, which is the light of the earth, when it casts forth its rays, as the eye upon the object that is seen; and the meaning is, that the locusts should be so thick between the heavens and the earth, that the eye of the earth, which is the sun, could not see or cast its rays upon it, as in Exo 10:15, and so Pliny says (a), that locusts came sometimes in such multitudes as to darken the sun:

and they shall eat the residue of that which is escaped, which remaineth unto you from the hail; particularly the wheat and the rye, or rice, which was not grown, Exo 9:32 and the herb or grass of the land, Exo 10:12.

and shall eat every tree which groweth for you out of the field; such fruit trees as escaped the hail, and such boughs and branches of them which were not broken off by it, Exo 10:15 and locusts will indeed eat trees themselves, the bark of them, and gnaw everything, even the doors of houses, as Pliny (b) relates.

(z) "oculum terrae", Montanus, Piscator; so Ainsworth. (a) Nat. Hist. l. 11. c. 29. (b) Nat. Hist. l. 11. c. 29.

to-morrow will I bring the locusts--Moses was commissioned to renew the request, so often made and denied, with an assurance that an unfavorable answer would be followed on the morrow by an invasion of locusts. This species of insect resembles a large, spotted, red and black, double-winged grasshopper, about three inches or less in length, with the two hind legs working like hinged springs of immense strength and elasticity. Perhaps no more terrible scourge was ever brought on a land than those voracious insects, which fly in such countless numbers as to darken the land which they infest; and on whatever place they alight, they convert it into a waste and barren desert, stripping the ground of its verdure, the trees of their leaves and bark, and producing in a few hours a degree of desolation which it requires the lapse of years to repair.
