21Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon they servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are.
22And I 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 thou mayest know that I am Jehovah in the midst of the earth.
23And I will put a division between my people and thy people: by to-morrow shall this sign be.
24And Jehovah 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.
25And Pharaoh called for Moses and for Aaron, and said, Go ye, sacrifice to your God in the land.
26And Moses said, It is not meet so to do; for we shall sacrifice the abomination of the Egyptians to Jehovah our God: lo, shall we sacrifice the abomination of the Egyptians before their eyes, and will they not stone us?
27We will go three days` journey into the wilderness, and sacrifice to Jehovah our God, as he shall command us.
