What did the Magicians tell Pharaoh after witnessing the third plague of Egypt?

This is the finger of God

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.

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.

Then the magicians said unto Pharaoh, This is the finger of God. Exodus 8:17-19
