22I will set apart in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end you may know that I am Yahweh in the midst of the earth.
23I will put a division between my people and your people: by tomorrow shall this sign be."`"
24Yahweh did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants` houses: and in all the land of Egypt the land was corrupted by reason of the swarms of flies.
25Pharaoh called for Moses and for Aaron, and said, "Go, sacrifice to your God in the land!"
26Moses said, "It isn`t appropriate to do so; for we shall sacrifice the abomination of the Egyptians to Yahweh our God. Behold, shall we sacrifice the abomination of the Egyptians before their eyes, and won`t they stone us?
27We will go three days` journey into the wilderness, and sacrifice to Yahweh our God, as he shall command us."
28Pharaoh said, "I will let you go, that you may sacrifice to Yahweh your God in the wilderness, only you shall not go very far away. Pray for me."
