Exodus 8:20-27

20And Jehovah said to Moses, Rise up early in the morning, and stand before PharaohH6547 — behold, he will goH935 out to the water — and say to him, ThusH3651 saith Jehovah, Let my people goH935, that they may serve me.

21For, if thou do not let my people go, behold, I will send dog-flies upon thee, and upon thy bondmen, and upon thy people, and into thy houses; and the houses of the Egyptians shall be full of dog-flies, and also the groundH776 on which they are.

22And I will distinguish in that day the land of Goshen, in which my people dwell, that no dog-flies shall be there; that thou mayest know that I Jehovah am in the midst of the land.

23And I will put a separation between my people and thy people; to-morrow shall this sign be.

24And Jehovah did so; and there came dog-flies in a multitude into the house of PharaohH6547, and [into] the houses of his bondmen; and throughout the land of Egypt, the land was corrupted by the dog-flies.

25And PharaohH6547 called MosesH4872 and Aaron, and saidH559, GoH3318, sacrificeH2076 to your 1God in the land.

26And MosesH4872 said, It is not proper to do so; for we should sacrifice the abomination of the Egyptians to Jehovah our 2God: lo, if we sacrificed the abomination of the Egyptians before their eyes, would they not stone us?

27We will go three days' journey into the wilderness, and sacrifice to Jehovah our 3God, as he shall command us.
