Authorized King James Version
"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]."
— Exodus 8:21, Authorized King James Version
And the magicians did so with their enchantments to bring forth lice, but they could not: so there were lice upon man, and upon beast.
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.
And the LORD did so; and there came a grievous swarm [of flies] into the house of Pharaoh, and [into] his servants' houses, and into all the land of Egypt: the land was corrupted by reason of the swarm [of flies].
