And the LORD said unto Moses, Rise up early in the morning, and stand before Pharaoh; lo, he cometh forth to the water; and say unto him, Thus saith the LORD, Let my people go, that they may serve me. Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon thy servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are. Exodus 8:20-21

So now comes time for the 4th Plague, the Flies. As we read in our last 3 plagues, Pharaoh has lied to God and told him he would allow the Israelites to leave, however he then hardens his heart and keeps the Hebrews captive. To this point, Pharaoh has witnessed many signs and wonders performed by God, however no matter how much evidence he sees, his heart remains hard and he rejects God

There are some scholars who believe this insect might have actually been a biting beetle or a dog flie. Either way , I’m sure we have all been bit by a fly before, imagine thousands of them in your house, biting and swarming you. This plague was obviously more than just destroying the land, this was to inflict some pain on the people as judgement

We also need to remember , the Egyptians worshipped many gods. So they most likely believed they were under punishment from their pagan gods. They probably cried out to their false deities but never heard an answer. As God is revealing their is only One true living God

Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon thy servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are. And I will sever in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am the LORD in the midst of the earth. Exodus 8:21-22

Notice God is going to do this plague a little differently also, He’s not going to just invade all of the land, he is going to spare the land of Goshen , where the Isralietes live and spare them this torment. This is further revelation into Gods intelligent design, this isn’t just a random act of infestation, God is in complete control of this plague

And I will put a division between my people and thy people: to morrow shall this sign be. And the LORD did so; and there came a grievous swarm of flies into the house of Pharaoh, and into his servants’ houses, and into all the land of Egypt: the land was corrupted by reason of the swarm of flies. Exodus 8:23-24

So God is going to make a clear distinction between the Israelites and the Egyptians in this plague, could this be a foreshadow of the Rapture? Whatever it is, God is displaying his sovereignty and is in complete control of this plague

And Pharaoh said, I will let you go, that ye may sacrifice to the LORD your God in the wilderness; only ye shall not go very far away: intreat for me. Exodus 8:28

At this time, Moses asks Pharaoh to allow the Israelites to go into the wilderness and make a sacrifice for Yahweh, at first Pharaoh is hesitant, but then it almost seems like he may be coming to repentance. Here we see Pharaoh ask Moses to intercede for him between him and God.

Remember we have an intercessor between us and the Father and its Jesus Christ, another foreshadow here in Moses

And Pharaoh hardened his heart at this time also, neither would he let the people go. Exodus 8:32

But after all was said and done, Pharaoh again lied to God and said he would allow the Israelites to leave, however after God removed the plague, he hardened his heart and went back to his evil ways

You cant say that God is not patient and merciful, all Pharaoh had to do was truly repent and God would have spared him the wrath, and its the same for us. Repent and receive Christ as your Lord and be spared the wrath of Hell Amen!
