Then the magicians said unto Pharaoh, This is
the finger of God: and Pharaoh's heart was hardened, and he hearkened not unto them; as the LORD had said.
And the LORD said unto Moses, Rise up early in the morning, and stand before Pharaoh; lo, he cometh forth to the water; and say unto him, Thus saith the LORD, Let my people go, that they may serve me.
Else, if thou wilt not let my people go, behold, I will send swarms of flies
upon thee, and upon thy 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.
And I will sever 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
the LORD in the midst of the earth.
And I will put a division between my people and thy people: to morrow shall this sign be.
