8. And the LORD spake unto Moses and unto Aaron, saying,
9. When Pharaoh shall speak unto you, saying, Shew a wonder for you: then thou shalt say unto Aaron, Take thy rod, and cast it down before Pharaoh, that it 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 rod before Pharaoh and before his servants, and it became a serpent.
11. Then Pharaoh also called for the wise men and the sorcerers: and they also, the magicians of Egypt, did in like manner with their enchantments.
12. For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods.
13. And Pharaoh's heart was hardened, and he hearkened not unto them; as the LORD had spoken.
