n°2 / Exodus 8 :

18And the magicians did so with their enchantments to bring forth lice, but they could not : so there were lice upon man, and upon beast.
19Then 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.
20And 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.
