1 God told Moses, "Look at me. I'll make you as a god to Pharaoh and your brother Aaron will be your prophet. You are to speak everything I command you, and your brother Aaron will tell it to Pharaoh. Then he will release the Israelites from his land. At the same time I am going to put Pharaoh's back up and follow it up by filling Egypt with signs and wonders. Pharaoh is not going to listen to you, but I will have my way against Egypt and bring out my soldiers, my people the Israelites, from Egypt by mighty acts of judgment. The Egyptians will realize that I am God when I step in and take the Israelites out of their country." 6 Moses and Aaron did exactly what God commanded. Moses was eighty and Aaron eighty-three when they spoke to Pharaoh.
8 Then God spoke to Moses and Aaron. He said, "When Pharaoh speaks to you and says, 'Prove yourselves. Perform a miracle,' then tell Aaron, 'Take your staff and throw it down in front of Pharaoh: It will turn into a snake.'" 10 Moses and Aaron went to Pharaoh and did what God commanded. Aaron threw his staff down in front of Pharaoh and his servants, and it turned into a snake. 11 Pharaoh called in his wise men and sorcerers. The magicians of Egypt did the same thing by their incantations: each man threw down his staff and they all turned into snakes. But then Aaron's staff swallowed their staffs. 13 Yet Pharaoh was as stubborn as ever - he wouldn't listen to them, just as God had said.
