Exodus 8:20

Ex 8:20-32. Plague of Flies.

20-24. Rise up early ... Pharaoh; lo, he cometh forth to the water, &c.--Pharaoh still appearing obdurate, Moses was ordered to meet him while walking on the banks of the Nile and repeat his request for the liberation of Israel, threatening in case of continued refusal to cover every house from the palace to the cottage with swarms of flies--while, as a proof of the power that accomplished this judgment, the land of Goshen should be exempted from the calamity. The appeal was equally vain as before, and the predicted evil overtook the country in the form of what was not "flies," such as we are accustomed to, but divers sorts of flies (Psa 78:45), the gad fly, the cockroach, the Egyptian beetle, for all these are mentioned by different writers. They are very destructive, some of them inflicting severe bites on animals, others destroying clothes, books, plants, every thing. The worship of flies, particularly of the beetle, was a prominent part of the religion of the ancient Egyptians. The employment of these winged deities to chastise them must have been painful and humiliating to the Egyptians while it must at the same time have strengthened the faith of the Israelites in the God of their fathers as the only object of worship.

Pharaoh was early at his false devotions to the river; and shall we be for more sleep and more slumber, when any service to the Lord is to be done? The Egyptians and the Hebrews were to be marked in the plague of flies. The Lord knows them that are his, and will make it appear, perhaps in this world, certainly in the other, that he has set them apart for himself. Pharaoh unwillingly entered into a treaty with Moses and Aaron. He is content they should sacrifice to their God, provided they would do it in the land of Egypt. But it would be an abomination to God, should they offer the Egyptian sacrifices; and it would be an abomination to the Egyptians, should they offer to God the objects of the worship of the Egyptians, namely, their calves or oxen. Those who would offer acceptable sacrifice to God, must separate themselves from the wicked and profane. They must also retire from the world. Israel cannot keep the feast of the Lord, either among the brick-kilns or among the flesh-pots of Egypt. And they must sacrifice as God shall command, not otherwise. Though they were in slavery to Pharaoh, yet they must obey God's commands. Pharaoh consents for them to go into the wilderness, provided they do not go so far but that he might fetch them back again. Thus, some sinners, in a pang of conviction, part with their sins, yet are loth they should go very far away; for when the fright is over, they will turn to them again. Moses promised the removal of this plague. But let not Pharaoh deal deceitfully any more. Be not deceived; God is not mocked: if we think to cheat God by a sham repentance and a false surrender of ourselves to him, we shall put a fatal cheat upon our own souls. Pharaoh returned to his hardness. Reigning lusts break through the strongest bonds, and make men presume and go from their word. Many seem in earnest, but there is some reserve, some beloved, secret sin. They are unwilling to look upon themselves as in danger of everlasting misery. They will refrain from other sins; they do much, give much, and even punish themselves much. They will leave it off sometimes, and, as it were, let their sin depart a little way; but will not make up their minds to part with all and follow Christ, bearing the cross. Rather than that, they venture all. They are sorrowful, but depart from Christ, determined to keep the world at present, and they hope for some future season, when salvation may be had without such costly sacrifices; but, at length, the poor sinner is driven away in his wickedness, and left without hope to lament his folly.
