The magicians

it is interesting that the magicians could do the same things with their rods to become serpents, with water to change it to blood, and bring up frogs:

Ex. 7:12 "For they cast down every man his rod, and they became serpents: but Aaron’s rod swallowed up their rods."

Ex. 7:22 "And the magicians of Egypt did so with their enchantments: and Pharaoh’s heart was hardened, neither did he hearken unto them; as the LORD had said."

Ex. 8:7 "And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt."


Now, they could not bring up lice from the dust

Ex. 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."

There is no register of the magicians doing anything like swarm of flies

It is not written but maybe they did swarm of flies.They did copy the other plagues. But i think not to the extend what God did but a much smaller copy and not the same way.
