5 When I raise my powerful hand and bring out the Israelites, the Egyptians will know that I am the lord.”
6 So Moses and Aaron did just as the lord had commanded them.
7 Moses was eighty years old, and Aaron was eighty-three when they made their demands to Pharaoh.
8 Then the lord said to Moses and Aaron,
9 “Pharaoh will demand, ‘Show me a miracle.’ When he does this, say to Aaron, ‘Take your staff and throw it down in front of Pharaoh, and it will become a serpent.’”
10 So Moses and Aaron went to Pharaoh and did what the lord had commanded them. Aaron threw down his staff before Pharaoh and his officials, and it became a serpent!
11 Then Pharaoh called in his own wise men and sorcerers, and these Egyptian magicians did the same thing with their magic.
