Exodus 08 The plague of lice

Exodus 08
The plague of lice
16 And the LORD said unto Moses, Say unto Aaron, Stretch out thy rod and smite the dust of the earth, that it may become lice throughout all the land of Egypt.
17 And they did so; for Aaron stretched out his hand with his rod, and smote the dust of the earth, and it became lice in man and beast; all the dust of the earth became lice throughout all the land of Egypt.
18 And the magicians also did so with their enchantments to bring forth lice, but they could not; and there were lice on man and beast.
19 Then said the Pharaoh the magicians: This is the finger of God. But Pharaoh's heart was hardened, and not heard them, as the Lord had said.
