And the LORDspake unto Moses and unto Aaron,saying ,
When Pharaoh shall speak unto you, saying , Shew a miracle for you: then thou shalt say unto Aaron,Take thy rod, and cast it beforePharaoh, and it shall become a serpent.10
And Moses and Aaron went in unto Pharaoh, and they did so as the LORD had commanded : and Aaron cast down his rodbeforePharaoh, and before his servants, and it became a serpent.11
Then Pharaoh also called the wise men and the sorcerers : now the magicians of Egypt, they also did in like manner with their enchantments.12
For they cast down every man his rod, and they became serpents: but Aaron'srod swallowed up their rods.13
And he hardenedPharaoh'sheart, that he hearkened not unto them; as the LORD had said .
