8:18 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.

8:19 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.

8:20 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.

8:21 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.

8:22 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.

8:23 And I will put a division between my people and thy people: to
morrow shall this sign be.

8:24 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.

8:25 And Pharaoh called for Moses and for Aaron, and said, Go ye,
sacrifice to your God in the land.
