22. But on that day I will give special treatment to the land of Goshen, where My people are living; no flies will be there. This way you will know that I, Yahweh, am in the land.
23. I will make a distinction between My people and your people. This sign will take place tomorrow.”
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.
25. Then Pharaoh summoned Moses and Aaron and said, “Go sacrifice to your God within the country.”
26. But Moses said, “It would not be right to do that, because what we will sacrifice to the Lord our God is detestable to the Egyptians. If we sacrifice what the Egyptians detest in front of them, won’t they stone us?
27. We must go a distance of three days into the wilderness and sacrifice to the Lord our God as He instructs us.”
