A judgment, and a mercy
The Flies
The fourth plague fills Egypt with swarms of flies, and for the first time God draws a line. Where His people dwell, in Goshen, no swarm will come.
“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 8:24
What happened
What happened. God sent Moses to meet Pharaoh again in the morning by the water, warning that if he would not let Israel go, "I will send swarms of flies upon thee" (Exodus 8:21). Then the LORD announced something new, "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 8:22). He would "put a division between my people and thy people" (Exodus 8:23). The swarms came grievously, and "the land was corrupted by reason of the swarm of flies" (Exodus 8:24). Pharaoh offered a compromise, that Israel sacrifice within the land, then that they go only a little way. Moses refused the half-measures and interceded, and the LORD removed every fly; "there remained not one" (Exodus 8:31). "And Pharaoh hardened his heart at this time also, neither would he let the people go" (Exodus 8:32). Again relief only stiffened his rebellion.
What it meant
What it meant. The great new feature of this plague is division. From here on God separates His people from the plagues, sparing Goshen so that Pharaoh would know the LORD is present "in the midst of the earth" (Exodus 8:22). This was proof that the plagues were no natural accident but the deliberate acts of a God who distinguishes those who are His. Some scholars connect the swarms to Egyptian insect deities, and beetle imagery such as the scarab was indeed woven into Egyptian religion, so a link is often suggested. That connection is a plausible inference and no more; Exodus names no such god here and gives only the general word, "against all the gods of Egypt I will execute judgment" (Exodus 12:12). The clearer lesson is the severing of Goshen and Pharaoh's answer to it, the offer of partial obedience. He tried to bargain God down to a sacrifice that cost him little. Moses would not accept a compromise, and neither will God accept a divided surrender.
How it points to Christ
How it points to Christ. The dividing of Goshen from Egypt is a picture of God's people set apart and kept in the day of judgment. This division reaches its fullness at Passover, where the blood on the door marks whose house is passed over. "Christ our passover is sacrificed for us" (1 Corinthians 5:7), and it is His blood that now divides the redeemed from the condemned, not their address or ancestry. In Christ, God still puts a division, calling His people to "come out from among them, and be ye separate" (2 Corinthians 6:17). Pharaoh's offer of partial obedience is the counterfeit the world still whispers, to serve God a little without leaving Egypt. But the Lamb who "taketh away the sin of the world" (John 1:29) calls for a full deliverance, out of bondage and into life.
Questions people ask
Why did God spare Goshen from this plague?
So Pharaoh would know the LORD acts deliberately and "is in the midst of the earth" (Exodus 8:22). By putting a division between His people and Egypt (Exodus 8:23), God showed the plagues were targeted judgments, not natural disasters.
What were the compromises Pharaoh offered?
He first told Israel to sacrifice within Egypt, then to go only a short distance (Exodus 8:25-28). Moses refused both. God required a complete departure to worship, not a convenient half-measure.
