Exodus chapter 7

Aaron's Staff Becomes a Snake

 8 The LORD said to Moses and Aaron, 9 "When Pharaoh says to you, 'Perform a miracle,' then say to Aaron, 'Take your staff and throw it down before Pharaoh,' and it will become a snake."

 10 So Moses and Aaron went to Pharaoh and did just as the LORD commanded. Aaron threw his staff down in front of Pharaoh and his officials, and it became a snake. 11 Pharaoh then summoned wise men and sorcerers, and the Egyptian magicians also did the same things by their secret arts: 12 Each one threw down his staff and it became a snake. But Aaron's staff swallowed up their staffs. 13 Yet Pharaoh's heart became hard and he would not listen to them, just as the LORD had said.

 19 The LORD said to Moses, "Tell Aaron, 'Take your staff and stretch out your hand over the waters of Egypt—over the streams and canals, over the ponds and all the reservoirs'-and they will turn to blood. Blood will be everywhere in Egypt, even in the wooden buckets and stone jars."

 20 Moses and Aaron did just as the LORD had commanded. He raised his staff in the presence of Pharaoh and his officials and struck the water of the Nile, and all the water was changed into blood. 21 The fish in the Nile died, and the river smelled so bad that the Egyptians could not drink its water. Blood was everywhere in Egypt.

 22 But the Egyptian magicians did the same things by their secret arts, and Pharaoh's heart became hard; he would not listen to Moses and Aaron, just as the LORD had said. 23 Instead, he turned and went into his palace, and did not take even this to heart.

 5 Then the LORD said to Moses, "Tell Aaron, 'Stretch out your hand with your staff over the streams and canals and ponds, and make frogs come up on the land of Egypt.' "

 6 So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land. 7 But the magicians did the same things by their secret arts; they also made frogs come up on the land of Egypt.

Notice two things:

Moses and Aaron by God were the originators of each miracle, i.e. staff turning into a snake, water to blood, etc.  Pharaoh’s magicians were imitations.  Satan always must imitate or deceive – nothing truly his own. 

Also, God’s miracles rule over Satan’s magic (whatever name or form Satan gives it – voodoo, wiccan – whatever).  Aaron’s snake ate the Egyptians magician’s.  And, notice here that even when the magician’s could duplicate some of the miracles (always on a much smaller scale) they could not rid the country of the plague, i.e. Moses and Aaron by God turn the river Nile and all water in Egypt to blood.  The magician’s perform a copy on a small scale (they couldn’t have even found much clean water to do this since God turned ALL water to blood), and they could do NOTHING to remedy the situation.  ALL the water still remained BLOOD until Moses cried out to God.

God is superior in every way.  This was the point in Egypt.  Each of the plagues was directed at a specific Egyptian diety/god.  There was no problem of unbelief in god’s or spirituality in their day, but rather “Who is the most powerful God?”

Exodus chapter 8

8 Pharaoh summoned Moses and Aaron and said, "Pray to the LORD to take the frogs away from me and my people, and I will let your people go to offer sacrifices to the LORD."

 9 Moses said to Pharaoh, "I leave to you the honor of setting the time for me to pray for you and your officials and your people that you and your houses may be rid of the frogs, except for those that remain in the Nile."

 10 "Tomorrow," Pharaoh said.
      Moses replied, "It will be as you say, so that you may know there is no one like the LORD our God. 11 The frogs will leave you and your houses, your officials and your people; they will remain only in the Nile."

 12 After Moses and Aaron left Pharaoh, Moses cried out to the LORD about the frogs he had brought on Pharaoh. 13 And the LORD did what Moses asked. The frogs died in the houses, in the courtyards and in the fields. 14 They were piled into heaps, and the land reeked of them. 15 But when Pharaoh saw that there was relief, he hardened his heart and would not listen to Moses and Aaron, just as the LORD had said.

Now notice this, after the first few miracles God did not allow the magicians to duplicate the miracles with their magic anymore.  Even the magicians cried out to Pharoah that it was “the Hand of God!”

The Plague of Gnats

 16 Then the LORD said to Moses, "Tell Aaron, 'Stretch out your staff and strike the dust of the ground,' and throughout the land of Egypt the dust will become gnats." 17 They did this, and when Aaron stretched out his hand with the staff and struck the dust of the ground, gnats came upon men and animals. All the dust throughout the land of Egypt became gnats. 18 But when the magicians tried to produce gnats by their secret arts, they could not. And the gnats were on men and animals.

 19 The magicians said to Pharaoh, "This is the finger of God." But Pharaoh's heart was hard and he would not listen, just as the LORD had said.

Exodus is great stuff for magic vs. Miracles!
