5 And the Egyptians shall know that I am the Lord when I stretch forth My hand upon Egypt and bring out the children of Israel from among them.”
6 So Moses and Aaron did it. Just as the Lord commanded them, so they did.
7 Moses was eighty years old, and Aaron was eighty-three years old when they spoke to Pharaoh.
8 Now the Lord spoke to Moses and to Aaron, saying,
9 “When Pharaoh shall speak to you, saying, ‘Show a miracle,’ then you shall say to Aaron, ‘Take your rod, and throw it before Pharaoh,’ and it shall become a serpent.”
10 So Moses and Aaron went to Pharaoh, and they did what the Lord had commanded. And Aaron threw 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. Then the magicians of Egypt likewise performed with their secret arts.
