Exodus 8:20-32 - Plague Four: Flies
20 The Lord said to Moses, “Get up early in the morning and present yourself to Pharaoh when you see him going out to the water. Tell him: This is what Yahweh says: Let My people go, so that they may worship
24 And the Lord did this. Thick swarms of flies went into Pharaoh’s palace and his officials’ houses. Throughout Egypt the land was ruined because of the swarms of flies.
26 But Moses said, “It would not be right
28 Pharaoh responded, “I will let you go and sacrifice to the Lord your God in the wilderness, but don’t go very far. Make an appeal
29 “As soon as I leave you,” Moses said, “I will appeal to the Lord, and tomorrow the swarms of flies will depart from Pharaoh, his officials, and his people. But Pharaoh must not act deceptively again by refusing to let the people go and sacrifice to the Lord.” 30 Then Moses left Pharaoh’s presence and appealed to the Lord. 31 The Lord did as Moses had said: He removed the swarms of flies from Pharaoh, his officials, and his people; not one was left. 32 But Pharaoh hardened his heart this time also and did not let the people go.
