Advertising
Short answer: Proverbs 20:14 says, "It's no good, it's no good," says the buyer; but when he is gone his way, then he boasts. That verse does not exempt the seller; it sets the standard for both sides of a sale. Advertising is often a form of speech aimed at influencing a choice, and the buyer's words in this proverb are a kind of speech too, spoken in one direction while the heart runs in another. Scripture treats such double speech as an offense against God, not merely against a trading partner. It does not forbid persuasion, description, or even enthusiasm about a product. It forbids misrepresentation: false claims, hidden defects, invented urgency, and words that contradict what the speaker actually knows. The standard is not negativity but truth, and the same honesty that governs a seller down to the scale and the measure applies to every promotion.
What the buyer is actually doing in Proverbs 20:14
The proverb gives us a small, sharp scene. A buyer inspects goods and announces, "It's no good, it's no good," says the buyer; but when he is gone his way, then he boasts. The buyer is not offering a sincere appraisal. He is using language as leverage, saying one thing in the transaction and rejoicing in his cleverness once the deal is closed. The proverb is not about the goods at all. It is about the gap between the spoken word and the true intention.
The buyer is manipulating the seller's estimate of value. We may not know if he believes the item is genuinely inferior, but the second half of the verse makes his purpose clear: he exaggerates the defect to lower the price. The seller, of course, faces a mirror temptation: to hide faults, inflate quality, or create a false sense of scarcity so the buyer pays more than the thing deserves. The proverb simply chooses the buyer's side of the transaction, likely because that is the form deception most often takes in ordinary market life.
What makes this proverb more than folk wisdom is the way Scripture classifies it. Lying in the marketplace is not categorized as ordinary business sense or a harmless custom. It is placed in the same category as false scales and dishonest measurements, which Proverbs 11:1 says are an abomination to Yahweh. The text does not single out one profession over another; it reaches all speech that trades on someone else's ignorance.
Why advertising is not exempt from Proverbs 20:14
Advertising is a form of communication and, therefore, a form of speech. It can truthfully present a product, explain how it works, compare it with alternatives, and help a buyer find what they actually need. None of that is dishonest. But the proverb targets exactly what much advertising is designed to do: create a gap between what is said and what is true in order to move a person toward a purchase.
The buyer in the proverb used words to lower a seller's confidence. A dishonest ad uses words to raise a buyer's confidence beyond what the facts support. Both are misrepresentation for advantage. Scripture addresses the buyer's tactic directly in Proverbs 20:14, and the same standard, argued from the character of God, binds the seller and advertiser. Ephesians 4:25 says, "Therefore putting away falsehood, speak truth each one with his neighbor. For we are members of one another." The command is not limited to church gatherings; it is grounded in the fact that we belong to one another.
A person who writes ad copy is speaking to a neighbor. A person who approves a campaign is choosing what a neighbor will believe. A platform that runs the ad is distributing a claim. The proverb's buyer was not condemned for buying; he was condemned for saying what he did not believe. The advertiser is in the same position.
False weights, short measures, and modern marketing
Proverbs 11:1 states, "A false balance is an abomination to Yahweh, but accurate weights are his delight." The scale was the tool of trade, and tampering with it was a way to steal invisibly. The buyer in Proverbs 20:14 manipulates with words; the merchant in Proverbs 11:1 manipulates with equipment. Both produce the same result: the other party agrees to a trade based on a false picture of reality.
Micah 6:10-11 asks, "Are there yet treasures of wickedness in the house of the wicked, and a short ephah that is accursed?" A short ephah is a measuring container made smaller than the standard, so a seller gives less grain than the price assumes. Again, the deception is built into the medium of exchange. Modern advertising has its own versions of short measures: a price that hides fees until checkout, a warranty stripped of its real coverage, a before-and-after image that has been altered, a countdown timer that resets, a testimonial purchased from someone who never used the product.
Not every technique is deception. Not every exaggeration is a lie. But the categories in Scripture make us ask a plain question: does the buyer understand what they are actually getting? If the words, images, or omissions are designed to produce a false understanding, the short ephah is present, even if no one is standing at a grain bin.
Persuasion is not the same thing as deception
Some readers conclude from Proverbs 20:14 that all advertising is dishonest. That overreads the text. The proverb does not condemn negotiating; it condemns speaking one thing and believing another. Abraham negotiated over a burial site, and no condemnation follows. Jesus asked questions and told parables that moved listeners toward a decision. Persuasion that respects the hearer's ability to weigh the truth is not the sin described here.
The difference is whether the truth is available to the person being persuaded. A well-made case for a good product leaves the buyer with accurate information and the freedom to decline. Deception withholds or distorts what the buyer needs in order to choose rightly. The buyer in Proverbs 20:14 did not give the seller an honest picture of his own judgment. He presented distaste while privately calculating gain.
Christians may therefore work in marketing, write copy, design campaigns, and sell products, provided they tell the truth. The command in Colossians 3:9-10 is, "Don't lie to one another, seeing that you have put off the old man with his doings," and the old man's habits include precisely this reflexive bending of facts for advantage. The new life in Christ does not make a person naive about commerce; it makes them truthful in it.
Selling a product you know is poor
The proverb raises a second question. Is it only the words that must be true, or the product itself? A seller may say only accurate things about a bad product and still mislead by selection, emphasis, and omission. Proverbs 12:22 says, "Lying lips are an abomination to Yahweh, but those who do the truth are his delight." The phrase do the truth suggests that truth is not merely a statement but a practice, a way of conducting oneself in a transaction.
If a product has known flaws, advertising that buries those flaws under a mountain of favorable claims is a species of the buyer's tactic in Proverbs 20:14, just deployed by the other party. The seller says in effect, this is excellent, while knowing it is not. The remedy is disclosure proportionate to the risk: clear terms, honest limitations, and claims that match what the product actually does.
This does not require a merchant to advertise every competitor's advantages or to describe a product in the most negative terms possible. It requires that the buyer not be misled about what they are purchasing. Faithful Christians may differ on how much disclosure is required in a given market, but the direction of the Bible's command is not ambiguous: no false balance, no short ephah, no lying lips.
What Scripture does not say about advertising
Proverbs 20:14 does not condemn commerce, profit, or the desire to persuade. It does not say that a buyer must accept the first price, that a seller must volunteer every weakness, or that enthusiasm in presenting a product is itself a lie. It also does not give a detailed code for pricing, packaging, or platform algorithms. Those are matters of wisdom and prudence, and faithful believers will apply the principle differently in different contexts.
The passage also does not limit honesty to religious settings. A frequent and dangerous misreading treats marketplace speech as a separate moral zone where ordinary rules of truth are relaxed. That is exactly the assumption Proverbs 20:14 overturns. The buyer's deception occurs in an ordinary transaction, not in a courtroom or a sanctuary, and it is still recorded as folly and sin.
Another misreading turns the proverb into a club against sellers alone. The verse specifically describes a buyer. The application runs both ways, and a Christian who sells must be as careful as a Christian who buys. The God who delights in accurate weights is not impressed by a clever campaign or a shrewd negotiation when the truth has been bent to win.
How to apply this when you write, sell, or buy
Begin with the plain question the proverb forces: does my speech match what I actually believe and know? Before you publish a claim, ask whether it would survive being read aloud in the presence of the person it is meant to persuade. If the answer is no, the words need to change. This is not a market strategy; it is the practice of Ephesians 4:25, which anchors truth-telling in our shared membership in one another.
Then ask a second question about the buyer: what will they understand from this? An ad can be technically accurate and still mislead through framing, omission, or a suggested result the product cannot deliver. The honest advertiser wants the buyer's understanding to match reality, not merely to remain technically defensible. This is the meaning of doing the truth in Proverbs 12:22, not just avoiding provable falsehoods.
Finally, apply the proverb to yourself as a buyer. Haggling is not forbidden, but speaking contempt for a thing in order to lower a price, then boasting about the deal, is the exact behavior the proverb names. Christians are free to negotiate, but not to misrepresent. The standard is the same on both sides of the counter: true words, true measures, true delight in what God delights in.
Biblical fidelity check
The passage establishes that God sees and judges deceptive speech in ordinary commerce. It names a specific tactic: the buyer who calls goods worthless to lower a price, then boasts once the deal is done. It does not establish a complete manual for advertising, pricing, or negotiation, and it does not condemn profit or persuasion as such. It also does not claim that every exaggeration or every hard bargain is the same sin; wisdom is required to weigh context and effect. What it does establish is the moral seriousness of misrepresentation, which the surrounding passages reinforce with the language of abomination and delight.
A common misreading is that the proverb only condemns lying in explicitly religious settings, as though business were governed by a lower standard. That reading is wrong because the text places the deception in an ordinary market exchange and ties it to the character of God, who hates a false balance and a short measure. Another misreading is that the verse forbids advertising altogether. That is also wrong; the verse condemns deception, not communication. The correct reading distinguishes persuasion that respects the buyer's understanding from manipulation that corrupts it.
Other passages that speak to Proverbs 20:14
Proverbs 20:14 does not stand alone; Scripture speaks repeatedly about truth in commerce, community, and the new life in Christ. Proverbs 11:1 contrasts the false balance with accurate weights, and Micah 6:10-11 exposes the short ephah and the treasures of wickedness. Ephesians 4:25 commands believers to put away falsehood and speak truth, while Colossians 3:9-10 tells them not to lie to one another because they have put off the old man.

Frequently asked questions
Does Proverbs 20:14 mean all advertising is lying?
No. The proverb condemns a specific kind of deception: saying a thing is worthless while intending to buy it cheap and then boast. It does not condemn commerce, persuasion, or even enthusiasm about a product. Advertising that accurately describes what a product does and what it costs is not the sin described here. The line is crossed when words or omissions are designed to produce a false understanding in the buyer for the seller's advantage. That is misrepresentation, and Scripture treats it as a serious offense against God, not merely against the other party in the transaction.
How do I advertise honestly if my product has flaws?
Be truthful about what the product does and be clear about meaningful limitations. Scripture does not require advertising to be self-accusing or to highlight every competitor, but it does require that the buyer not be misled about what they are purchasing. If a defect could reasonably change a buyer's decision, disclose it plainly. If a claim cannot be supported, remove it. The standard of Proverbs 12:22, that those who do the truth are God's delight, means honesty is a practice, not merely a set of technically true statements.
Is haggling itself wrong?
No. Negotiating is not condemned in Scripture, and examples of respectful bargaining appear without moral rebuke. What Proverbs 20:14 condemns is the specific deception of speaking false contempt for goods in order to lower the price. A buyer may offer less than the asking price and give true reasons for the offer. A buyer may not pretend the item is worthless while believing the opposite, then boast about the trick. The line is between negotiating over price and misrepresenting what you actually know and think about the item.
