Aaron stretched out his hand with his rod, and smote the dust of 
the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.
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...
Exodus 8:17-19
"The 3rd plague, of lice (or gnats or mosquitoes) from the dust of the earth, confronted all the gods of the earth (e.g. Akhor)."
