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.
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.
