When Moses first confronted Pharaoh, the king asked:
“Who is the LORD, that I should obey him and let Israel go?”
— Exodus 5:2
Exodus 7 begins God’s public answer.
Pharaoh believes he possesses unquestionable authority. He controls the government, economy, military, religion, and Israelite labor force. He considers himself accountable to no one.
But Moses is not returning with a human army. He is returning with the word of YHWH.
The signs and plagues are not random miracles. They are acts of revelation and judgment. Through them, God will demonstrate:
Pharaoh is not the highest ruler.
Egypt’s gods cannot protect the nation.
Creation belongs to YHWH.
Israel belongs to YHWH.
Oppression will not continue without judgment.
God’s covenant promise will be fulfilled.
The central question is not whether Moses is more impressive than Pharaoh. The question is whether Pharaoh will submit to the LORD.
“Then the LORD said to Moses, ‘See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet.’”
This statement must be interpreted carefully.
God is not turning Moses into a divine being. Moses remains human, sinful, dependent, and accountable to God.
The statement describes Moses’ representative authority.
Moses will stand before Pharaoh as God’s commissioned representative.
Pharaoh previously asked:
“Who made you ruler and judge?”
The answer is now clear: God has appointed Moses.
Moses does not possess authority because of:
Egyptian education
Hebrew ancestry
Personal courage
Public approval
Natural eloquence
His authority comes from the God who sent him.
When Moses delivers God’s message faithfully, Pharaoh is not merely rejecting Moses. He is rejecting the God whose word Moses communicates.
The Hebrew word translated “prophet” is navi.
A prophet is someone appointed to communicate a message received from God.
In this arrangement:
God speaks to Moses.
Moses gives the message to Aaron.
Aaron speaks publicly to Pharaoh.
Pharaoh receives the word of God.
Aaron is Moses’ “prophet” in the sense that he serves as Moses’ spokesman.
This arrangement helps us understand biblical prophecy. A true prophet does not invent the message. The prophet faithfully communicates what God has spoken.
God says:
“You are to say everything I command you.”
Moses may not soften the message to make it more acceptable to Pharaoh.
He may not remove:
God’s claim over Israel
The command to release the people
The warning of judgment
The call to worship
The revelation of God’s name
A servant of God does not own God’s message. He is entrusted with it.
“You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. But I will harden Pharaoh’s heart.”
God prepares Moses for continued opposition.
The next confrontation will not immediately produce Israel’s release. Pharaoh will resist, and God will multiply His signs and wonders.
The Hebrew verb in verse 3 is connected with qashah, meaning to make hard, stubborn, or difficult.
Elsewhere, Exodus uses additional words:
Chazaq — to strengthen or make firm
Kaved — to be heavy or unresponsive
The different words describe Pharaoh becoming increasingly resistant to God’s command.
God is not taking a humble, innocent king and forcing him to become evil.
Before the plagues begin, Pharaoh has already:
Enslaved Israel
Imposed ruthless labor
Ordered the death of Hebrew boys
Rejected the name of the LORD
Refused Israel’s worship
Increased the people’s burdens
Accused God’s message of being a lie
Pharaoh’s heart is already opposed to God.
God’s hardening can be understood as judgment. God confirms Pharaoh in the rebellious direction Pharaoh has chosen.
As the conflict continues, Exodus will say:
Pharaoh hardened his heart.
Pharaoh’s heart became hard.
God hardened Pharaoh’s heart.
All three descriptions are important.
Pharaoh acts according to his own proud desires and remains responsible. At the same time, his rebellion cannot escape God’s sovereignty.
God does not lose control when Pharaoh resists. God will use Pharaoh’s resistance to reveal His power, justice, and covenant faithfulness.
God says:
“Though I multiply my signs and wonders in Egypt, he will not listen to you.”
This is a sobering truth.
People sometimes say, “If God would only perform an undeniable miracle, everyone would believe.”
Pharaoh will witness extraordinary signs, yet continue resisting.
Miracles can reveal divine power, but they do not force a proud heart to love or submit to God.
Greater evidence can produce greater responsibility without producing repentance.
“Then I will lay my hand on Egypt and with mighty acts of judgment I will bring out my divisions, my people the Israelites.”
Pharaoh believes Israel is securely held under his power.
God says He will lay His own hand upon Egypt.
The contrast is intentional:
Pharaoh’s hand enslaves.
God’s hand delivers.
Pharaoh’s hand strikes the Hebrews.
God’s hand strikes the oppressive system.
Pharaoh’s hand appears powerful.
God’s hand is supreme.
The plagues are called “mighty acts of judgment.”
They are not uncontrolled displays of anger. They are judicial acts against:
Pharaoh’s rebellion
Egypt’s idolatry
Economic exploitation
Violence against children
Refusal to recognize God
The enslavement of God’s people
God gave Pharaoh a clear command. Pharaoh knowingly refused.
Each confrontation provides another opportunity for Pharaoh to submit, but each refusal brings greater judgment.
God calls Israel:
“My divisions, my people.”
The word “divisions” can describe organized groups or hosts.
Israel entered Egypt as an extended family of seventy. God will bring them out as a great people organized by tribes and divisions.
They are not Pharaoh’s disorganized slave population. They are the covenant people and host of the LORD.
“The Egyptians will know that I am the LORD.”
The purpose of the plagues includes revelation.
God intends to reveal His identity to:
Pharaoh
Pharaoh’s officials
The Egyptian population
Israel
Future generations
The surrounding nations
Knowledge of God can come through salvation or judgment.
Israel will know the LORD as Redeemer. Egypt will know Him as Judge.
The same revelation produces different experiences depending on the heart’s response.
“Moses and Aaron did just as the LORD commanded them.”
This statement marks significant growth in Moses.
Previously, Moses repeatedly objected:
“Who am I?”
“What if they do not believe?”
“I cannot speak.”
“Please send someone else.”
“Why would Pharaoh listen to me?”
Now Moses and Aaron obey.
The text emphasizes:
“They did just as the LORD commanded.”
Faithful service is measured by obedience, not by immediate visible success.
Moses was eighty years old, and Aaron was eighty-three when they spoke to Pharaoh.
God’s call is not limited to youth.
Moses’ life can be viewed in three major forty-year periods:
Approximately forty years in Egypt
Approximately forty years in Midian
Approximately forty years leading Israel
At eighty, Moses is beginning the central public assignment of his life.
No season is wasted when God uses it for preparation.
God anticipates that Pharaoh will say:
“Perform a miracle.”
Pharaoh does not ask for a sign because he is ready to believe. He treats Moses and Aaron as challengers who must prove their authority.
God instructs Aaron to throw down his staff before Pharaoh.
The Hebrew word in Exodus 7 is tannin.
This word can describe:
A great serpent
A large reptile
A sea creature
A dragon-like creature
Possibly a crocodile in an Egyptian setting
Exodus 4 used the more common word nachash, meaning snake. Here the stronger word may emphasize a larger or more threatening creature.
The precise species is less important than the theological point: God transforms the staff into a living creature under His authority.
Serpents and cobras were associated with Egyptian royal power. Pharaoh’s crown often displayed a cobra symbol representing protection and authority.
Crocodiles also carried religious significance in Egypt.
The sign therefore occurs in a cultural setting where powerful reptiles could represent royal or divine power.
God demonstrates that whatever Egypt honors or fears remains under His control.
Moses and Aaron obey. Aaron throws down the staff, and it becomes a great serpent.
Pharaoh then summons his wise men, sorcerers, and magicians.
The Hebrew word often translated “magicians” is chartummim.
These men probably belonged to Egypt’s educated religious class. They may have practiced:
Ritual magic
Divination
Incantations
Secret religious arts
Court wisdom
Techniques designed to imitate supernatural events
The New Testament identifies two opponents of Moses as Jannes and Jambres:
“Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth.”
— 2 Timothy 3:8
Those names do not appear in Exodus but were preserved in later Jewish tradition known to Paul and his readers.
The text says the magicians did the same things “by their secret arts.”
Several explanations have been suggested:
Deceptive performance or illusion
Skilled handling of snakes
Occult or demonic power
Some combination of deception and supernatural evil
The passage does not explain the precise mechanism.
We should affirm what the text emphasizes: the magicians produced a convincing imitation, but their power was limited and subordinate.
Scripture teaches that evil spiritual powers are real, but they are never equal to God.
This is not a battle between two equally powerful gods. The LORD stands alone as Creator.
The magicians do not deny that something supernatural has happened. They imitate it.
This teaches that not every extraordinary event comes from God.
Counterfeit spirituality often attempts to reproduce the appearance of divine power while resisting divine truth.
The proper question is not merely:
“Is this impressive?”
We must also ask:
What message does it support?
Whom does it glorify?
Does it agree with God’s Word?
Does it lead toward obedience to Christ?
What kind of spiritual fruit does it produce?
“But Aaron’s staff swallowed up their staffs.”
— Exodus 7:12
The verb translated “swallowed” is bala‘.
The sign demonstrates complete superiority.
The Egyptian magicians can imitate the transformation, but they cannot prevent their staffs from being swallowed.
This is a preview of the entire plague conflict:
Egypt may resist.
Egypt may imitate.
Egypt may appear powerful.
But Egypt cannot overcome the LORD.
The act also communicates judgment against Egyptian claims of power. The symbol of God’s authority consumes the symbols of Egypt’s authority.
Later, the sea will overwhelm Pharaoh’s forces. Egypt’s power will again be swallowed by an act of God.
Aaron’s staff does not simply become one more serpent among many.
It swallows the others.
God is not presenting Himself as another deity competing for a place within Egypt’s religious system. He is revealing His unique supremacy over it.
“Yet Pharaoh’s heart became hard and he would not listen to them, just as the LORD had said.”
The sign does not produce repentance.
Pharaoh has seen:
God’s messenger
God’s command
A supernatural sign
The defeat of his magicians’ staffs
Yet he refuses to listen.
This is not an intellectual problem alone. It is a moral and spiritual problem.
Pharaoh does not want to release Israel because obedience would cost him:
Labor
Wealth
Control
Reputation
Religious supremacy
Political authority
Sometimes people claim they need more evidence when the deeper issue is unwillingness to surrender.
Pharaoh’s resistance does not surprise God.
The repeated phrase reminds the reader that God remains in control.
Nothing is proceeding outside His knowledge.
“Then the LORD said to Moses, ‘Pharaoh’s heart is unyielding; he refuses to let the people go.’”
The word used here is related to kaved, meaning heavy.
Pharaoh’s heart is spiritually heavy, unresponsive, and resistant.
God sends Moses to meet Pharaoh in the morning as Pharaoh goes to the Nile.
Pharaoh may have gone to the river for:
A religious ritual
Personal bathing
Royal ceremony
Inspection
An ordinary daily activity
The text does not tell us precisely.
What matters is that God confronts Pharaoh at the river central to Egypt’s life and identity.
God tells Moses:
“Confront him on the bank of the Nile.”
The Hebrew idea involves placing oneself before Pharaoh.
Moses, who once fled from Pharaoh, now waits to confront Egypt’s king.
The difference is not that Moses has become fearless in himself. He now stands under God’s commission.
Moses must say:
“The LORD, the God of the Hebrews, has sent me to say to you: Let my people go, so that they may worship me in the wilderness.”
God’s command has not changed.
Pharaoh’s rejection does not cause God to negotiate away His rightful claim.
The purpose remains worship.
The issue is not merely:
“Will Pharaoh allow Israel to relocate?”
It is:
“Whom will Israel serve?”
God declares that Pharaoh has refused to listen.
Pharaoh cannot claim ignorance. He has heard the command and rejected it.
Divine judgment follows persistent refusal of revealed truth.
“This is what the LORD says: By this you will know that I am the LORD.”
Pharaoh asked:
“Who is the LORD?”
God now begins a series of answers.
The knowledge Pharaoh refused to receive through God’s word will now confront him through judgment.
This is a serious biblical principle: rejecting God’s revelation does not make God disappear. It changes how the person will experience His authority.
God says Moses will strike the water with the staff.
The results will be devastating:
The water will become blood.
The fish will die.
The river will stink.
The Egyptians will be unable to drink its water.
The text repeatedly calls the substance “blood.”
Some natural explanations have been proposed, such as red algae, sediment, or contamination. God can certainly use natural processes to accomplish His purposes.
However, the text presents the event as an extraordinary divine sign occurring:
At God’s announced time
Through the action God commanded
With comprehensive effects
As direct judgment
In a sequence of miraculous plagues
We should allow the passage to communicate its intended claim: God supernaturally turned Egypt’s waters into blood.
Egypt depended upon the Nile.
Without it, the nation could not easily sustain:
Agriculture
Food production
Animals
Human population
Transportation
Economic stability
The river’s annual flooding made Egypt agriculturally prosperous.
What Egypt regarded as a dependable source of life now becomes undrinkable and associated with death.
God reveals that creation’s gifts cannot be separated from the Creator who provides them.
Pharaoh had commanded:
“Every Hebrew boy that is born you must throw into the Nile.”
— Exodus 1:22
The Nile had been turned into a place of Hebrew death.
Now the river becomes blood.
The text does not explicitly say every detail of the plague is direct retaliation for the murdered children, but the connection is difficult to miss.
The river used in Pharaoh’s violence becomes an instrument of divine judgment.
God has seen the bloodshed.
Egyptians associated the Nile with various divine powers, including the deity Hapi, who was connected with the river’s flooding and fertility.
Other Egyptian gods were associated with:
The river
Fish
Fertility
Agriculture
Royal protection
The Bible later states that God executed judgments upon Egypt’s gods.
However, we should be cautious about claiming that every plague corresponds perfectly to one particular Egyptian deity. Egyptian religion was complex, and several gods could be associated with the same part of nature.
The broader theological point is clear:
Egypt trusts the Nile.
Egypt associates creation with its gods.
YHWH demonstrates sovereign authority over the river.
Egypt’s religious system cannot reverse His judgment.
The plagues expose every false object of trust.
God commands Aaron to stretch the staff over:
Streams
Canals
Ponds
Reservoirs
Stored water
Blood appears even in containers of wood and stone.
The description emphasizes the comprehensiveness of the judgment.
This is not a small discoloration at one part of the river. Egypt’s water supply is struck throughout the land.
Genesis 1 describes God bringing order, fruitfulness, and life.
The plagues begin to reverse Egypt’s experience of creation:
Water becomes blood.
Fish die.
The river stinks.
Life-giving creation becomes hostile.
The ordered environment begins to collapse.
This pattern is sometimes described as de-creation.
Egypt’s rebellion against the Creator leads to disorder within creation.
At the same time, God is preparing a new beginning for Israel. Judgment for Egypt accompanies liberation for God’s people.
“But the Egyptian magicians did the same things by their secret arts.”
Again, the text does not explain precisely how much water they affected or how the imitation occurred.
The central irony is that they reproduce the problem but cannot solve it.
They cannot:
Turn blood back into water
Restore the Nile
Save the fish
Remove the stench
Provide drinking water for Egypt
Force God to end the plague
Counterfeit power can imitate destruction but cannot bring true restoration.
Egypt does not need more blood. It needs clean water. The magicians cannot provide it.
Because the magicians produce an imitation, Pharaoh finds another reason not to submit.
People determined to resist God will often use any alternative explanation to protect their unbelief.
The imitation does not equal God’s act, but it gives Pharaoh enough excuse to ignore the message.
“Pharaoh’s heart became hard; he would not listen to Moses and Aaron, just as the LORD had said.”
Pharaoh returns to his palace and “does not take even this to heart.”
This is a frightening picture of spiritual hardness.
The nation’s water supply has been devastated. Fish are dying, the river stinks, and people cannot drink. Yet Pharaoh refuses to humble himself.
His concern for his authority is greater than his concern for the suffering of his people.
A hardened leader may allow others to suffer rather than admit personal wrongdoing.
“And all the Egyptians dug along the Nile to get drinking water, because they could not drink the water of the river.”
The Egyptians attempt to obtain filtered groundwater near the riverbank.
The verse emphasizes that the plague produced real hardship for ordinary Egyptians.
Pharaoh’s rebellion does not affect only Pharaoh. His decisions bring suffering upon the people he rules.
Sin is personal, but its consequences frequently spread through families, communities, organizations, and nations.
The Egyptians can dig for water, but they cannot restore the Nile.
Human effort may manage some consequences of judgment, but it cannot remove the deeper cause.
Egypt’s fundamental need is not improved digging. Pharaoh must listen to the LORD.
“Seven days passed after the LORD struck the Nile.”
The plague lasted long enough to demonstrate that this was not a brief illusion.
Seven days of:
Dead fish
Foul water
Thirst
Digging
Economic disruption
Visible judgment
Yet Pharaoh does not repent.
The verse also prepares for the next confrontation and plague.
God is giving time between judgments. Each stage creates another opportunity to recognize His authority.
God’s patience should lead to repentance, not further presumption.
Moses is “like God” to Pharaoh only because God has commissioned him.
Spiritual authority is never personal ownership. It remains accountable to God’s Word.
Egypt’s magicians can imitate signs, but they cannot defeat God, reverse His judgment, or create deliverance.
Not everything supernatural is holy. Spiritual claims must be tested by God’s revealed truth.
Pharaoh receives evidence but continues resisting.
The problem of unbelief is not always insufficient information. It can be unwillingness to surrender.
The plague is not random cruelty. It comes within a long history of slavery, murder, idolatry, and repeated refusal.
God’s justice means that evil will not rule forever without accountability.
The Nile is not independent. It belongs to the Creator.
Water, animals, land, human bodies, political rulers, and spiritual powers all remain under God’s authority.
God repeatedly says:
“You will know that I am the LORD.”
Exodus is the revelation of God’s identity through redemption and judgment.
Moses stood before Pharaoh as God’s commissioned representative. Aaron spoke as Moses’ prophet.
Jesus is greater.
He does not merely bring a message from God. He is the eternal Word who became flesh.
“Anyone who has seen me has seen the Father.”
— John 14:9
Moses could say, “This is what the LORD says.”
Jesus repeatedly declared:
“Truly I tell you…”
He spoke with divine authority because of who He is.
Aaron’s staff swallowed the magicians’ staffs, demonstrating God’s superiority over Egypt’s powers.
At the cross and resurrection, Jesus achieved the decisive victory over spiritual powers:
“Having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.”
— Colossians 2:15
Evil can imitate, deceive, accuse, and temporarily oppress. It cannot defeat the risen Christ.
The Nile’s blood reveals judgment and death. But later in Exodus, the blood of the Passover lamb will mark the homes of God’s people for protection.
These themes prepare us for the cross.
Christ’s blood exposes the seriousness of sin’s judgment while providing forgiveness for those who trust Him.
“The blood of Jesus…purifies us from all sin.”
— 1 John 1:7
The same holy God who judges sin provides the sacrifice through which sinners may be redeemed.
What does it mean that Moses was “like God to Pharaoh,” and why does this not mean Moses became divine?
Why were the Egyptian magicians’ imitations unable to equal God’s power, even though they appeared impressive?
What does Pharaoh’s response teach us about the limitations of miracles and evidence when the heart refuses to surrender?
Why was the Nile an especially meaningful place for God’s first plague and judgment?
How can believers test supernatural claims, spiritual experiences, or impressive religious leaders today?
Something can appear spiritual without coming from God.
Do not evaluate a ministry solely by:
Miraculous claims
Large crowds
Emotional intensity
Charismatic personality
Impressive stories
Predictions or signs
Test everything by Scripture, the gospel of Christ, the character of the messenger, and the spiritual fruit produced.
Pharaoh’s hardness grows throughout the conflict.
Each time we hear God’s truth, we are responsible for our response. Repeatedly saying “later” can train the heart to say “no.”
When God convicts us, the proper response is repentance, not delay.
Moses was eighty and Aaron was eighty-three.
God may call people to new forms of service after decades of preparation. Age may change how someone serves, but it does not remove the possibility of meaningful faithfulness.
The question is not merely, “How old am I?” but “What is God asking me to do faithfully now?”
The magicians reproduced the sign but could not restore the water.
Many false solutions behave the same way. They may distract, imitate relief, or produce excitement, but they cannot address the deepest problem of sin.
Only God can redeem, cleanse, and restore.
Pharaoh heard God’s word, saw God’s sign, experienced God’s judgment, and still returned to his palace unchanged.
The most dangerous response to God is not always open hostility. It may be continually hearing truth without allowing it to produce repentance.
When God reveals sin, do not merely admire the sermon, analyze the message, or discuss the evidence.
Listen to the voice of the Lord—and obey.
