Isaiah 44:19 Commentary: The Irrationality of Idolatry
Hebrew · 9 what the commentators say
Meaning in one sentence
Why do idolaters lack basic reasoning? This study of Isaiah 44:19 explores spiritual blindness, willful ignorance, and the absurdity of worshipping
Research Summary
- Meaning: The verse highlights the irrationality of idolatry: the same wood used for life’s necessities becomes the object of worship, yet the idolater lacks the basic reasoning to see the absurdity.
- Key words: yashiv (returns to the heart), lev (heart), da’at (knowledge), tevunah (understanding), chetziyo (half of it), to’evah (abomination), bul (produce/outgrowth), esgod (prostrate).
- Main debate: Is the blindness of the idolater mainly willful ignorance (Calvin, Gill) or a divine judicial hardening (Keil and Delitzsch, referencing Romans 1)? Most see a combination.
- Theological theme: Human depravity blinds our reasoning; only God’s illumination and grace can open our eyes to see the idolatry in our own hearts.
- Best use: A warning against spiritual complacency and a call to examine where we place our trust; useful for teaching on repentance, the first commandment, and the nature of sin.

And no one considers in his heart, no one has the knowledge or insight to say, “I burned half of it in the fire, and I baked bread on its coals; I roasted meat and I ate. Shall I make something detestable with the rest of it? Shall I bow down to a block of wood?”
WEB World English Bible 2000

KJV King James Version 1769
And none considereth in his heart, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh, and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree?
ASV American Standard Version 1901
And none calleth to mind, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree?

No discurre para consigo, no tiene sentido ni entendimiento para decir: Parte de esto quemé en el fuego, y sobre sus brasas cocí pan, asé carne, y comíla; ¿ he de tornar en una abominación lo restante de ello? ¿ delante de un tronco de árbol tengo de humillarme?
E nenhum deles pensa sobre isso em seu coração, e não tem conhecimento nem entendimento para dizer: A metade queimei no fogo; e aqueci pão sobre suas brasas; assei carne, e a comi; e faria eu do resto uma abominação? Prostraria eu ao que saiu de uma árvore?
Il ne rentre pas en lui-même,
und gehen nicht in ihr Herz; keine Vernunft noch Witz ist da, daß sie doch dächten: Ich habe auf den Kohlen Brot gebacken und Fleisch gebraten und gegessen, und sollte das übrige zum Greuel machen und sollte knieen vor einem Klotz?
En niemand van hen brengt het in zijn hart, en er is noch kennis noch verstand, dat hij zeggen zou: De helft daarvan heb ik verbrand in het vuur, ja, ook op de kolen daarvan heb ik brood gebakken, ik heb vlees daarbij gebraden, en heb het gegeten; en zou ik het overblijfsel daarvan tot een gruwel maken, zou ik nederknielen voor hetgeen van een boom gekomen is?
Nessuno rientra in se stesso, ed ha conoscimento e intelletto per dire: “Ne ho bruciata la metà nel fuoco, sui suoi carboni ho fatto cuocere il pane, v’ho arrostito la carne che ho mangiata, e farò col resto un’abominazione? e mi prostrerò davanti ad un pezzo di legno?”
I nie uważają tego w sercu swojem, nie mająż to umiejętności ani baczenia, aby rzekli: Część z niego spaliłem ogniem, a przy węglu jego napiekłem chleba, upiekłem mięso, i najadłem się; i mamże ja z ostatku jego obrzydliwość uczynić, a przed kloc em drewnianym klękać?
И не возьмет он этого к своему сердцу, и нет у него столько знания и смысла, чтобы сказать: "половину его я сжег в огне и на угольях его испек хлеб, изжарил мясо и съел; а из остатка его сделаю ли я мерзость? буду ли поклоняться куску дерева?"
誰 心 裡也不 醒悟，也沒有 知識，沒有 聰明，能說：「我曾拿一分 在火 中 燒了， 在 炭火 上烤過 餅；我也烤過 肉 吃。這剩下的，我豈要作 可憎的物嗎？我豈可向木 墩子 叩拜呢？」
And no one takes note, no one has enough knowledge or wisdom to say, I have put part of it in the fire, and made bread on it; I have had a meal of the flesh cooked with it: and am I now to make the rest of it into a false god? am I to go down on my face before a bit of wood?

Scholars' Consensus
Commentators across traditions agree that this verse exposes the sheer irrationality of idolatry. The Hebrew phrase translated “no one considers in his heart” (yashiv el lev) literally means “to bring back to the heart”, a call to reflect. But the idolater never does. Calvin notes that “unbelievers of their own accord cherish their ignorance” and “do not err merely through ignorance, but to rebellion.” Gill observes that the idolater “does not come to himself again, or return to his right mind.” Barnes adds that they had not “attentively and carefully thought on the folly of what they were doing.” The absurdity is laid bare: the same wood that cooked the meal is carved into a god. Yet the idolater lacks the basic reasoning to see it. Keil and Delitzsch link this to the judgment of hardness of heart (Isaiah 6:9, 10; Romans 1:28). The blindness is both willful and divinely imposed, a sobering warning about the spiritual stupor that sin produces.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Willful ignorance: Idolaters choose not to think; they 'flatter themselves in their error' (Calvin, Barnes).
- Divine hardening: God gives them over to their foolishness as judgment (Keil & Delitzsch, citing Romans 1:28 and Isaiah 6:9–10).
What is clear: The verse unequivocally condemns idolatry as irrational and abominable to God; idolaters lack the reasoning to see the contradiction.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Cause of spiritual blindness | Idolaters are responsible for their own failure to perceive. | Some emphasize willful suppression of truth (Calvin); others stress God’s active judicial hardening (Keil & Delitzsch). Both agree God is just. |
| Translation of 'bul' (H0944) | The word refers to something that comes from a tree. | Some translate it as 'block' or 'stock' (most English versions); others argue it means 'produce' or 'outgrowth' (Keil, Delitzsch, Gill) and reject 'block'. |
| Nature of the 'abomination' (to’evah) | Idols are detestable to God. | Some focus on the ritual impurity aspect (unclean); others on the ethical affront of robbing God of His glory. |
| Role of reasoning in faith | True faith involves right thinking, not irrational belief. | Some say reason alone can expose idolatry; others argue that only the Spirit opens eyes, so reason is insufficient to cure blindness. |
Historical & Cultural Context
Isaiah 44:19 sits within the prophet’s extended satire on idolatry (vv. 9, 20), likely written during the Assyrian crisis of the late 8th century BC. Judah’s neighbours, Assyrians, Babylonians, Phoenicians, made elaborate images of their gods from wood and metal. Isaiah’s satire works by describing the process with deadpan realism. A man selects a tree, plants it, watches it grow, then cuts it down. He burns half to warm himself and cook his meal. The other half he carves into an idol, falls down before it, and prays for deliverance (vv. 15, 17). Verse 18 declares that God has “shut their eyes, that they can’t see, and their hearts, that they can’t understand”, a judicial hardening in response to persistent rebellion. Verse 19 then delivers the punchline: no one thinks, no one has knowledge or understanding to say, “I burned half of it, baked bread on the coals, roasted meat and ate. Shall I make the rest of it an abomination? Shall I bow to a block of wood?” The word for “abomination” (to’evah) is the term the Bible uses for idols (1 Kings 11:5, 7; 2 Kings 23:13). The word translated “block of wood” (bul) means “produce” or “outgrowth”, literally “the produce of a tree” (so Keil and Delitzsch, Gill). It is not a trunk or stock, but something that grew. The irony is thick: the same rain that nourished the tree also watered the fields; the same fire that roasted the meat could have warned him. Yet he does not connect the dots. This verse is not just a polemic against ancient paganism. It exposes a universal human tendency: refusing to see the contradiction between depending on God’s provision and worshipping the provision itself.
Textual Notes
Reception History
Preaching This Verse
Three-point outline
- The Failure to Reflect: The Hebrew idiom “bring back to the heart” (yashiv el lev) shows that idolatry begins when we stop thinking critically about what we trust.
- The Absence of Knowledge and Understanding: Without da’at (knowledge) and tevunah (understanding), the idolater cannot see the obvious contradiction.
- The Unspoken Question: “Shall I bow down to a tree trunk?”, the one question that would shatter the illusion, but which the deceived heart never asks.
Five-point outline
- The process: wood used for fuel and food (vv. 15, 16).
- The residue: the leftover material (yitro) becomes an idol.
- The abomination: idols are to’evah, detestable to God (Deuteronomy 27:15).
- The missing logic: “no one thinks”, the verb shuv (return) implies a needed turning of the mind.
- The question: the idolater should ask “Shall I bow down?” but never does.
Illustration hooks
- A chef who uses half a pumpkin to make soup and then worships the other half as a god.
- Someone who uses a smartphone to navigate and then prays to it for guidance.
- A person who relies on the very resources God provides (time, health, money) and then treats those resources as ultimate.
Questions your congregation is asking
- Isn’t this just about wooden idols? What do modern idols look like?
- How can I tell if I have become spiritually blind to something in my own life?
- Why does God sometimes allow people to remain in their delusion?
Leading a Discussion
Isaiah 44:19 forces us to confront the irrational core of all idolatry, the refusal to apply simple logic to what we trust. As the prophet exposes the absurdity of worshipping a piece of wood, we are invited to examine the hidden idols in our own lives. These questions take the group from observing the text to reflecting on personal application.
Discussion questions
- What does the Hebrew idiom “bring back to the heart” tell us about how idolatry takes root?
- The idolater must think: “I burned half of it, I baked bread, I roasted meat, shall I make the rest an abomination?” Why is this reasoning so obvious, yet never carried out?
- In what ways might we treat created things as ultimate, putting our trust in money, relationships, status, or even religious routine?
- How does verse 18 (“God has shut their eyes”) challenge or comfort you? Is spiritual blindness always our own fault?
- What does it mean that idols are called “abomination”? How does that shape our view of sin?
- The text ends with an unspoken question: “Shall I bow down to a tree trunk?” What would it take for us to ask that question honestly about our own lives?
- How does the gospel, the good news that God redeems even those who have gone astray (Isaiah 44:22, 23), offer hope to idolaters?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Calvin's Commentaries Reformed 1564
Calvin insists that unbelievers are not genuinely ignorant but willfully so. They could easily recognize their folly if they paused to reflect, yet they deliberately avoid examining whether they are on the right path. Their blindness is not innocence but rebellion: they prefer to flatter themselves in error rather than face truth.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentary stresses the absurd self-deception of idolatry: the worshiper cannot apply basic reasoning to his own actions. His eyes are plastered over, and he is like a shepherd feeding on ashes, satisfied with something that can only disappoint his hope.
Geneva Bible Notes Reformed 1599
The Geneva note highlights the sheer irrationality of idolatry: a man uses wood to cook his food, then bows to what is left. The point is that such a person lacks even basic understanding, failing to see the absurdity of worshiping a piece of the same tree he just burned.
Gill's Exposition of the Bible Baptist 1748
Gill emphasizes that the idolater never pauses to think through what he is doing. Using part of a tree for warmth and food, he then bows to the leftover wood. This failure to reflect, Gill argues, shows a mind so darkened that it has abandoned rational reasoning entirely.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB emphasizes that the Hebrew word for "considereth" means to lay something seriously to heart, not just to notice it. They also highlight that "abomination" is the deliberate biblical term for an idol, signifying not mere detestability but the very essence of what provokes God's jealousy.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch sees the idolater's blindness as both a self-inflicted hardening and a divine judgment. God has given them over to a reprobate mind, smearing their eyes like plaster so they cannot see the absurd contrast between burning half a tree for bread and worshipping the leftover as a god.
Lange's Commentary Reformed 1857
Lange reads this promise as directed to the spiritual remnant, not the whole nation. He highlights the name Jeshurun as a term of endearment meaning "pious little one." The outpoured Spirit enables this remnant, including converted Gentiles pictured as grass among whom Israel grows, to confess the Lord and bear fruit.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry highlights the absurd contradiction in idolatry: a man uses part of a tree for fuel, then carves the remainder into a god and prays to it for deliverance. The idolater's own actions condemn him, for he trusts for help what he himself shaped from common wood.
