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.
14. And the LORD said unto Moses, Pharaoh's heart is stubborn, he refuseth to let the people go.
15. Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river's brink to meet him; and the rod which was turned to a serpent shalt thou take in thine hand.
