Yo, yo soy vuestro consolador. ¿ Quién eres tú para que tengas temor del hombre, que es mortal, del hijo del hombre, que por heno será contado?
Eu, eu sou aquele que vos consola; quem és tu, para que tenhas medo do homem mortal, ou do filho do homem que é como grama,
C’ est moi, c’ est moi qui vous console.
Ich, ich bin euer Tröster. Wer bist du denn, daß du dich vor Menschen fürchtest, die doch sterben, und vor Menschenkindern, die wie Gras vergehen,
Ik, Ik ben het, Die u troost; wie zijt gij, dat gij vreest voor den mens, die sterven zal? en voor eens mensen kind, dat hooi worden zal?
Io, io son colui che vi consola; chi sei tu che tu tema l’uomo che deve morire, e il figliuol dell’uomo che passerà com’erba;
Ja, Jam jest pocieszyciel wasz. Któżeś ty, że się boisz człowieka śmiertelnego, i syna człowieczego trawie podobnego?
Я, Я Сам - Утешитель ваш. Кто ты, что боишься человека, который умирает, и сына человеческого, который то же, что трава,
惟有 我，是 安慰你們的。你 是誰，竟怕 那必死 的人？怕那要變 如草 的世人？
I, even I, am your comforter: are you so poor in heart as to be in fear of man who will come to an end, and of the son of man who will be like grass?

Scholars' Consensus
Commentators agree that this verse forms the turning point in Isaiah 51, where God directly answers the plea for deliverance by declaring himself the sole comforter of his people. Barnes emphasizes the repetition of “I” as a deliberate intensification, meant to “impress deeply upon them the fact that their consolation came alone from God.” Keil and Delitzsch parse the logic: because Jehovah is the comforter, the church has no cause to fear. Gill expands on the nature of this comfort, God opening his heart and administering divine comforts by his Spirit, not merely through prophets. The rhetorical question “Who are you?” (מִי־אַתְּ) exposes the absurdity of fearing a mortal human (אֱנוֹשׁ) who dies, a creature as frail as grass (חָצִיר). Jamieson-Fausset-Brown connect the grass metaphor directly to Isaiah 40:6-8, grounding the argument in earlier prophecy. The consensus is firm: God's eternal, self-sufficient comfort renders all human threats trivial. The verse rebukes not the fact of suffering, but the misplaced fear that forgets the identity of the Comforter.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: God alone is the comforter of His people, and fearing mortal man is irrational given God's eternal nature and man's transience.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| The double 'I' emphasis | All commentators see it as emphatic, stressing that God alone is the comforter. | Some (e.g., Keil & Delitzsch) specify it as a strengthening of the subject; others (Barnes) focus on the psychological impression. No substantive disagreement. |
| Meaning of 'son of man' | Unanimously understood as 'human being', emphasizing mortality. | Minor: whether it carries messianic overtones; most agree it does not here, but see it as a generic term. |
| The fear being rebuked | All see the fear as inappropriate because of God's power and man's frailty. | Some (Gill) connect it specifically to the Roman persecutors; others (Cambridge) see it as general fear of oppressors in the exilic context. The underlying principle is the same. |
| Comfort as present or future | God's comfort is both a present reality and a future hope. | Matthew Henry emphasizes the prayer for deliverance as part of the comfort; others (Keil) focus on the immediate promise of release. Not a conflict, but varying emphases. |
Historical & Cultural Context
Isaiah 51 belongs to the “Book of Comfort” (chapters 40, 55), addressed to exiles in Babylon. The preceding verses (v.9, 11) contain a prayer for God to awake and act, recalling the exodus from Egypt. Now God responds. The historical situation is one of fear: the exiles are oppressed by a powerful empire, and they dread the fury of their captors. The prophet counters this by pointing to the Creator who stretched out the heavens and laid the foundations of the earth (v.13).
The imagery of grass (חָצִיר) directly echoes the opening of the comfort section (Isaiah 40:6-8), establishing a theme: all flesh is grass, but the word of God stands forever. The Hebrew words for “man”, אֱנוֹשׁ (mortal, frail) and בֶּן־אָדָם (son of man, human), both emphasize mortality. אֱנוֹשׁ in particular carries the connotation of weakness and sickness. The rhetorical question “Who are you?” (מִי־אַתְּ) does not ask for identity but for quality: “How can you, who have God as your comforter, be afraid of such a transient being?”
Lange notes the gender shift: feminine in verse 12 (Zion), masculine in verse 13 (Israel), showing the corporate address to the whole people. The phrase “the fury of the oppressor” in verse 13 further identifies the immediate threat, likely the Babylonian king, but the argument applies to any human power that sets itself against God's people. The comfort promised is not merely emotional; it is rooted in God's past acts of deliverance (the exodus, creation) and his covenant name, Yahweh of Armies.
Textual Notes
The supplied commentaries note no significant textual variants for Isaiah 51:12. The Hebrew text is stable, and the verse appears in all major manuscripts without notable differences. The wording in English translations is consistent across versions.
Reception History
Isaiah 51:12 has been treasured throughout church history as a word of courage for Christians facing persecution. Early church fathers referenced it to encourage believers to fear God rather than earthly rulers. During the Reformation, it was used to console those threatened by authorities. In worship, the contrast between God's eternal comfort and human frailty appears in hymns that echo the imagery of Isaiah 40. The verse continues to be a source of pastoral comfort for those intimidated by power, reminding the church that its true comforter is the Creator of the universe.
Preaching This Verse
Three-point outline
- “I, Even I, Am He”, The Unique Identity of the Comforter. God declares himself as the sole source of comfort. The double “I” is emphatic, insisting that no other power can give the reassurance his people need. This comfort is personal (you) and authoritative.
- “Who Are You?”, The Rebuke of Misplaced Fear. The rhetorical question challenges the believer's small perspective. Fear of mortal man forgets who God is and what he has done. It is a gentle but firm call to realign our vision.
- “Man Who Shall Die”, The Frailty of the Oppressor. Human threats are temporary. They are like grass that withers. The oppressor's fury cannot compare to God's power. Therefore, courage is not denial of danger but confidence in the greater One.
Five-point outline
- The Comforter's Self-Declaration (v.12a)
- The Rebuke of Fear (v.12b)
- The Frailty of Man (v.12c)
- The Question: “Where Is the Fury of the Oppressor?” (v.13)
- The Promise of Release (v.14)
Illustration hooks
- The fear of a loud boss who holds power over your job, but who will eventually retire or pass away. The comfort of knowing your ultimate security comes from God.
- The anxiety over political leaders or unstable governments, compared to the unchanging rule of the Creator who laid the foundations of the earth.
- The worry about a chronic illness or threat, while remembering that all human life is temporary. God’s comfort endures beyond any momentary trial.
Questions your congregation is asking
- “Why do I still get so afraid of people when I know God is in control?”
- “How can I hold onto God's comfort when my circumstances seem overwhelming?”
- “What does it mean that God alone comforts me? Does that mean I shouldn't seek comfort from others?”
Leading a Discussion
This verse confronts us with a choice: focus on the fleeting threats around us, or on the eternal God who promises to comfort us. As you discuss, let the weight of God’s self-declaration sink in. He does not simply send comfort; he is the Comforter.
Discussion questions
- Read Isaiah 51:12. Why do you think God repeats “I, even I”? What does this emphasize about him?
- The verse calls humans “man who shall die” and “son of man who will be made as grass.” What images come to mind? How do these contrast with God?
- Who is the “you” that God addresses? How would the original exilic audience have heard this question?
- In what ways can fear of people, even powerful people, cause us to “forget the Lord” (as verse 13 says)?
- Share an example where you felt afraid of what someone could do to you. How does this verse speak to that situation?
- The verse says God is “he who comforts you.” How have you experienced God's comfort in times of fear?
- What would it look like to live today as someone who truly believes that God's comfort outweighs any human threat?

What the Commentators Say
7 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes draws attention to the doubled "I" in the verse, which he sees as God's way of driving home that comfort comes from Him alone. The point is a stark contrast: God endures forever, but even the mightiest human being dies like cut grass.
Geneva Bible Notes Reformed 1599
God declares that He alone is the one who comforts His people. He then asks why anyone should fear mere mortals, who are as short-lived as grass. The point is the stark contrast between the eternal Comforter and fragile, temporary humanity.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that God promises to comfort his people directly by his Spirit and the immediate revelation of his love, not merely through prophets or ordinances. He then argues that believers have no reason to fear even the most terrifying persecutors, since all human enemies are frail, dying mortals whose power will end.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB notes that God comforts Zion by reminding her that her oppressors are merely mortal. They are "son of man," frail and dying like Adam, and will wither like grass. The comfort lies in contrasting man's fleeting power with God's enduring faithfulness.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch ground the promise in a logical argument: since Jehovah Himself is the church's comforter, His people have no reason to fear any mortal. They stress the absurdity of forgetting the almighty Creator out of terror for a man who will die like grass. The tormentor's fury will vanish, and the captive will be swiftly freed, sustained by Jehovah who stirs the sea.
Lange's Commentary Reformed 1857
Lange reads Isaiah 51 as a dramatic dialogue between four speakers: the veiled Servant of Jehovah, Israel, Jehovah Himself, and the prophet. The Servant opens by presenting the condition of redemption, calling Israel to look back to Abraham and Sarah as examples of faith.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry identifies the "arm of the Lord" in this prayer as either Christ himself or God acting directly. He clarifies that God never actually sleeps, so the call for him to "awake" is a plea for him to show visibly that he is watching over his people and ready to rescue them.
