20 And Jehovah said to Moses, Rise up early in the morning, and stand before Pharaoh—behold, he will go out to the water—and say to him, Thus saith Jehovah, Let my people go, that they may serve me. 21 For, if thou do not let my people go, behold, I will send dog-flies upon thee, and upon thy bondmen, and upon thy people, and into thy houses; and the houses of the Egyptians shall be full of dog-flies, and also the ground on which they are. 22 And I will distinguish in that day the land of Goshen, in which my people dwell, that no dog-flies shall be there; that thou mayest know that I Jehovah am in the midst of the land. 23 And I will put a separation between my people and thy people; to-morrow shall this sign be. 24 And Jehovah did so; and there came dog-flies in a multitude into the house of Pharaoh, and [into] the houses of his bondmen; and throughout the land of Egypt, the land was corrupted by the dog-flies. 25 And Pharaoh called Moses and Aaron, and said, Go, sacrifice to your God in the land. 26 And Moses said, It is not proper to do so; for we should sacrifice the abomination of the Egyptians to Jehovah our God: lo, if we sacrificed the abomination of the Egyptians before their eyes, would they not stone us? 27 We will go three days' journey into the wilderness, and sacrifice to Jehovah our God, as he shall command us. 28 And Pharaoh said, I will let you go, that you may sacrifice to Jehovah your God in the wilderness; only, go not very far away: intreat for me! 29 And Moses said, Behold, I go out from thee, and will intreat Jehovah; and the dog-flies will depart from Pharaoh, from his bondmen, and from his people, to-morrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to Jehovah. 30 And Moses went out from Pharaoh, and intreated Jehovah. 31 And Jehovah did according to the word of Moses; and he removed the dog-flies from Pharaoh, from his bondmen, and from his people; there remained not one. 32 And Pharaoh hardened his heart this time also, and would not let the people go.

(Read Exodus 8:20-32)
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.
