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.
16. And thou shalt say unto him, The Lord, the God of the Hebrews, hath sent me unto thee, saying, Let my people go, that they may serve me in the wilderness: and, behold, hitherto thou hast not hearkened.
17. Thus saith the Lord, In this thou shalt know that I am the Lord: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood.
18. And the fish that is in the river shall die, and the river shall stink; and the Egyptians shall loathe to drink water from the river.
