Overview
The fourth plague of Egypt involved swarms of flies that infested the land, causing great distress to the Egyptian people and their livestock. God distinctly protected the land of Goshen where the Israelites lived, demonstrating His sovereignty and care for His covenant people. Pharaoh repeatedly promised to let Israel go but hardened his heart, showing the futility of human resistance against God's purposes.
Key Scriptures
"Then the Lord said to Moses, 'Rise up early in the morning and present yourself before Pharaoh, as he comes out to the water, and say to him, Thus says the Lord, Let my people go, that they may serve me. Else, if you will not let my people go, behold, I will send swarms of flies on you and your servants and your people, and into your houses'" (Exodus 8:20-21, ESV).
"But on that day I will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, that you may know that I am the Lord in the midst of the earth" (Exodus 8:22, ESV).
Application
Trust that God's protection and purposes cannot be thwarted by human pride or resistance to His will.
