Exodus 7:8-13 - Aaron's Staff Becomes A Snake

⁸ And the LORD spoke to Moses, and to Aaron, saying, ⁹ When Pharaoh shall speak to you, saying, Show a miracle for you: then thou shalt say to Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent. ¹⁰ And Moses and Aaron went in to 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 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's rod swallowed up their rods. ¹³ And he hardened Pharaoh's heart that he hearkened not to them; as the LORD had said.
