14Then the LORD said to Moses, “Pharaoh’s heart is unyielding; he refuses to let the people go.
15Go to Pharaoh in the morning as you see him walking out to the water. Wait on the bank of the Nile to meet him, and take in your hand the staff that was changed into a snake.
16Then say to him, ‘The LORD, the God of the Hebrews, has sent me to tell you: Let My people go, so that they may worship Me in the wilderness. But you have not listened until now.
17This is what the LORD says: By this you will know that I am the LORD. Behold, with the staff in my hand I will strike the water of the Nile, and it will turn to blood.
18The fish in the Nile will die, the river will stink, and the Egyptians will be unable to drink its water.’”
19And the LORD said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt—over their rivers and canals and ponds and reservoirs—that they may become blood.’ There will be blood throughout the land of Egypt, even in the vessels of wood and stone.”
20Moses and Aaron did just as the LORD had commanded; in the presence of Pharaoh and his officials, Aaron raised the staff and struck the water of the Nile, and all the water was turned to blood.
21The fish in the Nile died, and the river smelled so bad that the Egyptians could not drink its water. And there was blood throughout the land of Egypt.

14Yahweh said to Moses, “Pharaoh’s heart is stubborn. He refuses to let the people go.
15Go to Pharaoh in the morning. Behold, he is going out to the water. You shall stand by the river’s bank to meet him. You shall take the rod which was turned to a serpent in your hand.
16You shall tell him, ‘Yahweh, the God of the Hebrews, has sent me to you, saying, “Let my people go, that they may serve me in the wilderness. Behold, until now you haven’t listened.”
17Yahweh says, “In this you shall know that I am Yahweh. Behold: I will strike with the rod that is in my hand on the waters which are in the river, and they shall be turned to blood.

Scholars' Consensus
Commentators agree this passage introduces the first of ten plagues as a direct challenge to Egypt's religion. The Nile was worshipped as a deity, so its transformation to blood was both a practical disaster and a theological humiliation. Clarke notes that Pharaoh's heart is described as kaved (heavy), indicating a dull, stubborn resistance that refuses to yield even to clear evidence. Barnes and Keil & Delitzsch emphasize that the plague was not a random act but a targeted sign: Yahweh was proving He is Lord over the Nile, Egypt's source of life and pride. The transformation was real, fish died, the river stank, and the Egyptians could not drink, not merely a discoloration. Gill argues that the death of the fish proves the change was genuine. The plague announces a pattern: Pharaoh's persistent refusal is met with escalating judgments that unmask the impotence of Egypt's gods.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Supernatural transformation: Literal blood; fish die, river stinks; miracles are by nature beyond natural explanation (Clarke, Gill).
- Intensified natural phenomenon: Nile naturally turns reddish during inundation; the plague supernaturally increased its degree and timing (Barnes, Keil & Delitzsch).
- Composite narrative: Literary analysis identifies J/E (Nile only) and P (all waters) traditions, explaining slight differences in scope.
- Human choice vs. divine hardening: Pharaoh first hardens his own heart (v.13); later God confirms that hardness as judgment (Ex. 10:1). Both are true.
What is clear: God is sovereign over the Nile and over Pharaoh; the plague was a real judgment that caused suffering and demonstrated Yahweh's power.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of the transformation | The change was real and devastating: fish died, the river stank, people could not drink. | Some see a purely supernatural change into literal blood; others see a miraculous intensification of natural discoloration (red sediment or organisms) that occurs at the inundation season. |
| Extent of the plague | The plague affected the Nile and its connected waters. | Proponents of J/E source read the plague as limited to the Nile (vv.17,20); proponents of P source see it extending to all waters in Egypt (v.19), including household vessels. |
| Pharaoh's hardening: human vs. divine | Pharaoh was responsible for his initial refusal, and God responded with judgment. | Some emphasize Pharaoh's own choice (Ex. 7:13-14); others emphasize that God hardened Pharaoh's heart as judicial punishment (Ex. 10:1,20,27). Both are present in the text. |
| Significance of the Nile as a target | The Nile was central to Egyptian life and was associated with their gods. | Some view the plague primarily as a practical disaster; others see it as a direct attack on the deity Hapi (the Nile god), making it a theological contest. |
Historical & Cultural Context
Pharaoh's morning trip to the Nile (v.15) was likely not a casual walk. The Nile was central to Egyptian identity: it provided water, fish, transportation, and the annual inundation that fertilized the fields. The Egyptians personified the Nile as Hapi, a god of abundance, and Pharaoh was considered its earthly guardian. The plague of blood struck at this very nerve.
Several commentators note that the timing may have been during the inundation season (June, July), when the river's water naturally turns reddish from sediment and microorganisms. Even so, they insist this event was supernatural: it happened at Moses's command, affected all water sources throughout Egypt, and devastated the ecosystem, fish died, the river stank, drinking water became impossible. Clarke cites ancient sources on the pleasantness of Nile water, making the plague especially repulsive.
The command to include water in vessels of wood and stone (v.19) shows the plague extended beyond the river itself to any stored water. This made escape from the plague impossible. Barnes explains that the various terms for waters, rivers, streams, ponds, pools, reservoirs, cover every fresh water source in Egypt. No water in the land was safe. The plague was total, underscoring Yahweh's absolute authority over every resource the Egyptians trusted.
Textual Notes
The supplied sources note no significant textual variants for Exodus 7:14-21. The major critical question is the composite nature of the passage: verses 17, 20 (Nile only) are assigned to the J/E source, while verses 19, 21b (all waters) belong to the Priestly source. These traditions were woven together by the final compiler. The resulting text is consistent and does not present a contradiction, the plague began at the Nile and spread to all Egypt's waters.
Reception History
Early Christian writers such as Origen saw the plague of blood as a type of the judgment that falls on those who refuse God's word. Augustine interpreted it as a sign that earthly goods become harmful when idolized. During the Reformation, Calvin used Pharaoh's hardened heart as a sobering example of human rebellion meeting divine punishment. Wesley applied it morally: when we trust creation more than the Creator, that very blessing can become a curse. The narrative has been sung in hymns about God's power over nature and preached as a warning against obstinate sin.
Preaching This Verse
Three-point outline
- The diagnosis of a heavy heart (v.14). God names the root of the conflict: Pharaoh's heart is stubborn, resistant to truth. This sets the stage for the plagues as both judgment and revelation.
- The confrontation at the Nile (vv.15-18). Moses meets Pharaoh at the object of his trust. The plague targets what Egypt worships, proving Yahweh's supremacy over counterfeit gods.
- The total reach of judgment (vv.19-21). No water is exempt, not rivers, not reservoirs, not household vessels. The plague demonstrates that sin's consequences touch every area of life.
Five-point outline
- God sees the heart (v.14). He discerns the true condition behind the surface.
- God prepares His messenger (vv.15-16). Moses is given specific instructions and the prophetic word.
- God declares His purpose (v.17). The plague is for knowing Yahweh, not just punishing Egypt.
- God judges what is trusted (vv.18-19). The Nile, source of life, becomes source of death.
- God carries out His word (vv.20-21). The plague happens exactly as promised, leaving no doubt.
Illustration hooks
- Trust betrayed. Think of a person who learns that a trusted resource, a water supply, a savings account, a relationship, has become toxic. The shock and helplessness are immense. Egypt felt that when the Nile turned to blood.
- Refusal to see. A student who has all the evidence for a correct answer but stubbornly clings to a wrong one. Pharaoh saw the miracle, heard the warning, but chose hardness anyway.
- Domino effect. One sin (refusing to let God's people go) leads to a cascade of consequences affecting the whole nation, fish die, water stinks, people suffer. Sin never stays private.
Questions your congregation is asking
- Does God cause people to have hard hearts, or do they harden themselves? The passage shows both: Pharaoh hardens his own heart initially (v.13), but later God confirms that hardness (Ex. 10:1). It is a mystery of human responsibility and divine sovereignty.
- Why don't miracles always bring people to faith? Pharaoh saw the Nile turn to blood and still refused to listen (v.22). Miracles can be explained away or met with greater rebellion.
- Is it fair to punish someone for a heart that God has hardened? The narrative shows God's justice and patience: Pharaoh was given many opportunities. The hardening is a judgment on a heart that has already chosen stubbornness.
Leading a Discussion
The first plague strikes at the heart of Egypt's pride: the Nile river. As you read Exodus 7:14-21, notice how God exposes what Pharaoh trusts and turns it into a source of suffering. The passage raises hard questions about stubbornness, divine judgment, and the purpose of signs.
Discussion questions
- Observation: What specific words does God use to describe Pharaoh's heart in verse 14? How does the Hebrew word kaved (heavy) shape your understanding?
- Observation: List every water source mentioned in verses 19 and 21. Why do you think the plague covered all of them?
- Interpretation: Why does God say the plague will happen so that Pharaoh will “know that I am Yahweh” (v.17)? What does this tell you about the purpose of the plagues?
- Interpretation: In what ways was the Nile a symbol of Egypt's strength and religion? How does striking it send a message about God's power?
- Application: Are there areas in your life where you trust something other than God, perhaps security, health, or reputation? What would it mean if that resource became a source of difficulty?
- Application: Pharaoh saw a clear miracle but hardened his heart. How do you respond when God makes His will obvious but you resist?
- Application: This plague affects innocent people (the Egyptian population) for the sin of their leader. How does that challenge or comfort you about God's justice in our world?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke focuses on the Hebrew word for hardened, cabed, which means heavy or stupid, showing Pharaoh’s willful refusal to be convinced despite overwhelming evidence. He also stresses the extraordinary pleasantness and healthfulness of the Nile’s water, making its transformation into real, foul blood far more devastating.
Barnes' Notes on the Bible Protestant 1832
Barnes highlights that the plague targeted Egypt's worshipped Nile, which was seen as the embodiment of the god Osiris. He notes that while the river naturally turns reddish at flood season, the miracle was distinct by its suddenness, its connection to Moses' word, and its lethal effects on fish and drinkability.
Calvin's Commentaries Reformed 1564
Calvin focuses on why God turned the Nile to blood instead of simply drying it up. A natural drought might have been mistaken for chance, but the visible, sudden corruption of Egypt's most vital resource was an unmistakable act of God that left human pride no excuse.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentary dissects the plagues as a layered composite from three sources (J, E, P), each describing distinct roles for Moses, Aaron, or God directly and different scopes of destruction. It concludes the narratives were shaped by centuries of oral tradition and hold moral and religious significance rather than exact historical record.
Gill's Exposition of the Bible Baptist 1748
Gill emphasises that the fish dying proved the water truly became blood, not just a discoloration. He notes Pharaoh likely went to the Nile that morning either to worship it as a god or to check its flood levels for agriculture. This plague was a direct judgment on Egypt’s deified river and a righteous retaliation for drowning Hebrew infants.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB stresses that the plague struck the Nile because it was Egypt's patron deity, the object of superstitious reverence and national pride. By turning the sacred river into blood, God directly humiliated their god in a way nothing else could, proving His supremacy over all Egypt's false gods.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch emphasize that the Nile plagues were not purely supernatural wonders but land-plagues Egypt occasionally experienced, raised to miracles by their unnatural timing, force, and sudden appearance at Moses' word. The first plague struck at the very moment Pharaoh was worshipping the Nile as a supreme deity, demonstrating that Jehovah, not Egypt's gods, truly ruled nature. The water turned blood-red in appearance rather than chemically, and the magicians likely imitated it using water already drawn before the plague struck.
Lange's Commentary Reformed 1857
Lange sees the water-to-blood miracle as a supernatural heightening of the Nile's natural seasonal reddening, not a chemical change into real blood. He notes that the magicians could produce the appearance of doing the same thing because the reddening continued to increase, and their deceptive tricks were enough to harden Pharaoh's heart.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley sees this plague as a just penalty for Egypt's idolatry: they worshipped the Nile itself, and they had stained it with the blood of Hebrew infants. Now God turns their cherished water to blood, showing that every creature becomes to us what He makes it. Sin is what turns our blessings into curses.
