Exodus 8:18

The magicians tried by their secret arts to produce gnats , but they could not . So there were gnats on man and beast .

But when the magicians tried to produce gnats by their secret arts, they could not. Since the gnats were on people and animals everywhere,

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.
