22. But on that day I will mark off the land of Goshen, where my people are staying, so that no swarms of flies will be there, that you may know that I am the Lord in the midst of this land.
23. I will put a division between my people and your people. This sign will take place tomorrow.”’”
24. The Lord did so; a thick swarm of flies came into Pharaoh’s house and into the houses of his servants, and throughout the whole land of Egypt the land was ruined because of the swarms of flies.
25. Then Pharaoh summoned Moses and Aaron and said, “Go, sacrifice to your God within the land.”
26. But Moses said, “That would not be the right thing to do, for the sacrifices we make to the Lord our God would be an abomination to the Egyptians. If we make sacrifices that are an abomination to the Egyptians right before their eyes, will they not stone us?
27. We must go on a three-day journey into the desert and sacrifice to the Lord our God, just as he is telling us.”
