16 Then the LORD said unto Moses, Say unto Aaron, Stretch out thy rod and smite the dust of the land, 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 in beast; all the dust of the land became lice throughout all the land of Egypt. 18 And the magicians did the same with their enchantments to bring forth lice, but they could not. And there were lice upon man and upon beast. 19 Then the magicians said unto Pharaoh, This is the finger of God. But Pharaoh’s heart hardened, and he did not hearken unto them as the LORD had said.
