21. Otherwise, if you will not let My people go, indeed I will send swarms of flies on you, and on your servants, and on your people, and into your houses. And the houses of the Egyptians shall be full of swarms of flies and also the ground wherever they are.
22. “ ‘I will in that day set apart the land of Goshen, in which My people dwell, so that no swarms of flies shall be there, in order that you may know that I am the Lord in the midst of the earth.
23. I will put a division between My people and your people. Tomorrow this sign will happen.’ ”
24. The Lord did so, and great swarms of flies came into the house of Pharaoh, and into his servants’ houses, and into all the land of Egypt. The land was corrupted because of the swarms of flies.
25. Pharaoh called for Moses and Aaron, and said, “Go, sacrifice to your God in the land.”
26. Moses said, “It is not right to do so, for what we shall sacrifice to the Lord our God would be an abomination to the Egyptians. If we shall sacrifice what is an abomination of the Egyptians before their eyes, will they not stone us?
