Jeremiah 9:23-24: Why the Wise Man Must Not Glory
Short answer: Jeremiah 9:23-24 records Yahweh's command that the wise man must not glory in his wisdom, the mighty man in his might, or the rich man in his riches. The reason is not that wisdom, strength, and wealth are evil in themselves, but that they cannot save, cannot secure the future, and cannot compare with knowing God. The same oracle names the one legitimate ground of boasting: understanding and knowing Yahweh, who exercises loving kindness, justice, and righteousness in the earth. The New Testament picks up this very text and applies it to the church, so the command is not an isolated proverb but a thread running from the prophets through Paul's letters to us.
The Setting: A People Confident in the Wrong Things
Jeremiah ministered in the last decades before Jerusalem fell to Babylon, and much of his book is a long, painful diagnosis of misplaced confidence. The people had the temple, the covenant, and a long history of God's protection, and they had turned those gifts into a charm against disaster. Jeremiah 7 records them saying the temple of Yahweh is here, as if the building guaranteed safety regardless of how they lived. Jeremiah 9 belongs to the same period and the same burden.
The three categories in the oracle, the wise, the mighty, and the rich, cover the main ways human beings build a sense of security. Wisdom is the advantage of the educated and the shrewd. Might is the advantage of the strong, the soldier, the well-connected. Riches are the advantage of the prosperous, the ones who can buy their way out of trouble. In a besieged city, all three of those advantages feel desperately important. Jeremiah speaks into that atmosphere and says none of them is the thing to boast in.
Notice the wording: do not let the wise man glory in his wisdom. The command is not do not be wise. It is do not glory. The Hebrew idea behind glorying is weightiness, the sense that a thing counts for you, that you lean on it, that your identity and hope rest on it. A man may possess wisdom and still not glory in it. The sin is the inner transfer of trust from God to the gift God gave. That transfer can happen quietly, without any external change at all.
Israel's history is full of this transfer. Solomon was the wisest man, and his later life shows how wisdom can coexist with a divided heart. Goliath was the mightiest man in the valley, and a shepherd boy with a sling answered him. The rich farmer in Jesus' parable planned bigger barns and heard that his soul would be required that night. Jeremiah's audience is not a special case; it is every human heart in a moment of crisis, reaching for whatever it has.
Why Wisdom, Might, and Riches Cannot Carry the Weight
The first reason is duration. Wisdom cannot see the future, only patterns and probabilities. Might cannot outlast the body that carries it; every soldier ages, every empire falls. Riches cannot be carried past death, and Proverbs itself warns about the uncertainty of wealth. Jeremiah later says that riches make themselves wings and fly away. When the Babylonians came, the counselors' advice failed, the soldiers' strength broke, and the gold was carried off to a foreign treasury.
The second reason is scope. Even a very wise person has limits built into being human. Isaiah 55:8-9 says, "For my thoughts are not your thoughts, and your ways are not my ways," says Yahweh. The verse does not only say that God is smarter; it says his categories and priorities are different in kind, as high as the heavens above the earth. Human wisdom can build an empire and still miss the point of existence. It can answer many questions and remain blind to the one that matters most.
The third reason is moral. Wisdom, might, and riches are all powers, and power in the hands of sinners is dangerous. A clever person can deceive more effectively. A strong person can oppress more thoroughly. A rich person can buy silence, courts, and armies. Jeremiah's generation did exactly that. So the problem is not merely that these gifts are fragile; it is that glorying in them produces injustice, and God has said plainly that he will not overlook it forever.
None of this makes wisdom, strength, or wealth sinful. Scripture praises the fear of the Lord as the beginning of wisdom, honours courage, and calls wealth a gift from God when it is used rightly. But every one of these good gifts becomes an idol the moment it becomes the ground of our confidence. The command is against glorying, against the settled assumption that these things are what make us safe. That assumption is what Jeremiah is dismantling, and it is the assumption we are most tempted to keep.
The One Boast God Permits: Knowing Him
After forbidding three boasts, the oracle names the one that stands. Let him who glories glory in this: that he understands and knows me, that I am Yahweh who exercises loving kindness, justice, and righteousness in the earth, for in these things I delight, says Yahweh. This is one of the most important sentences in the prophetic literature because it identifies knowing God himself, not merely knowing truths about him, as the highest human good.
The three words describing God's activity are carefully chosen. Loving kindness is covenant loyalty, the steadfast love that will not let go. Justice is the fair dealing that defends the weak and summons the powerful to account. Righteousness is God's own uprightness worked out in history. This is not a vague spirituality or a private feeling. It is the knowledge of a God who consistently acts in the world on behalf of his covenant, and who tells us that this is what he delights in.
That word delight matters. It is not only a command to us but a disclosure of God's own heart. He takes pleasure in showing covenant love, in doing justice, in acting rightly. To know him, then, is to be shaped by what he loves. A person who truly knows this God will begin to care about the things God cares about, which is precisely why the knowledge of God is the antidote to glorying in our own assets. The more we see him, the smaller our own credentials look.
This is also a hopeful text. Jeremiah spends the bulk of his book announcing judgment, and here, in the middle of it, God says what he wants his people to possess. He is not simply taking away their supports and leaving them empty. He is offering himself as the replacement. The command against boasting is not asceticism for its own sake; it is an invitation to a greater treasure than wisdom, strength, or money could ever be.
What Paul Does With This Text
Paul quotes this very oracle twice. In 1 Corinthians 1:31, after describing how God chose the foolish, weak, and lowly to shame the wise and strong, he concludes with the phrase from Jeremiah: let him who boasts, boast in the Lord. In 2 Corinthians 10:17-18 the same words appear again, this time in the context of Paul defending his ministry against rivals who measured themselves by their own standards.
The Corinthian church was full of boasting. They boasted in particular teachers, in spiritual gifts, in eloquence, in status. Paul's response is not to boast in the opposite direction, in how unimpressive he is. He applies Jeremiah: the only boasting that survives God's judgment is boasting in the Lord. And the reason given in 2 Corinthians is decisive: not he who commends himself is approved, but whom the Lord commends. Self-assessment ultimately counts for nothing because God is the one who evaluates.
Paul also knew the temptation from the inside. He had every credential an ancient Jewish man could want, and he lists them in Philippians 3 before calling them rubbish compared with knowing Christ. That language is not masochism; it is the same logic as Jeremiah. When you have seen the worth of knowing God, everything else is re-valued. The gifts are not hated; they are simply dethroned from the place only God can hold.
It is worth noting that Paul does not tell the Corinthians to stop being wise, strong, or influential. He tells them where to put their confidence. 1 Corinthians 3:18-21 goes further: let no one deceive himself, and if anyone thinks he is wise in this world, let him become a fool, that he may become wise. The path to real wisdom runs through admitting that our wisdom is not sufficient, which is humbling and, by the world's standards, foolish.
How This Looks in Ordinary Life
The command touches the mind first. For a thoughtful person, the temptation is to treat one's own analysis as final, to trust the model, the plan, the well-reasoned argument, and to treat prayer as a formality added afterward. The remedy is not to think less but to think with a settled awareness that our reasoning is finite and often self-serving. Proverbs 3:5-7 says, "Trust in Yahweh with all your heart, and don't lean on your own understanding." Leaning is the key image; the verse forbids making our understanding the load-bearing wall.
The command touches strength and influence next. Anyone with a measure of power, a position, a platform, a strong body, or a network of relationships faces the same temptation in a different key. It is easy to begin to believe that outcomes depend on us, that we must control, that our competence is what holds things together. The remedy is to use the strength fully while refusing to rest on it, to work hard and hold the results loosely, and to be quick to acknowledge that every ability is received.
The command touches money. For the wealthy, the temptation is to believe that resources equal safety, that enough money can insulate against any crisis. Jeremiah's world shows how fast that illusion collapses. For those with little, the temptation is the mirror image: envy, or the belief that money would solve everything. Both are forms of glorying in riches, one by possession and one by longing. The answer is contentment and generosity, which are simply the practical shape of trusting God rather than wealth.
And the command touches reputation. Much of our boasting is not verbal; it is the quiet management of how we are seen. We curate, compare, and quietly keep score. The remedy is to live before God rather than before an audience, to be content with his approval, and to let our sense of worth rest on the fact that we are known by him. That is the glory Jeremiah commends, and it is available to the unimpressive, the weak, and the poor, which is exactly the point.
Seeing God as the Ground of All Confidence
The positive side of this passage deserves its own attention. Jeremiah does not simply say stop boasting; he says boast in this, that you understand and know me. The knowledge of God is presented as a genuine possession, something a person can have and grow in. It is not reserved for scholars or prophets. It is offered to the ordinary Israelite in a besieged city, and to the ordinary Christian reading these words centuries later.
Growing in that knowledge involves both the word and the world. God has revealed himself in Scripture, so knowing him requires patient attention to what he has said about himself, including the unflattering parts. And God has revealed himself in his actions, so knowing him involves noticing how he has dealt with people, how he keeps covenant, how he defends the weak, how he is slow to anger. The three words in the oracle, loving kindness, justice, and righteousness, are not abstractions; they are the pattern of his dealings, and we learn them by watching him work.
There is a practical test that flows from this. If we truly know the God who delights in justice and righteousness, our own lives will begin to bend that way. A person who boasts in knowing God will care about how they treat employees, how they speak about opponents, whether they defend the vulnerable, and whether their business dealings are honest when no one is watching. The knowledge of God is not a private comfort; it is a shaping reality.
This is why Jeremiah places the command and the invitation side by side. He could have ended with the prohibition and left the people stripped of their confidence. Instead he gives them something better to stand on. The wise man loses nothing by refusing to glory in his wisdom, because he gains the God who gave him the wisdom. The mighty man loses nothing by refusing to glory in his might, because the strength of God is available to him. That exchange is the heart of the passage.
Biblical fidelity check
What the passage establishes is clear: God forbids glorying in wisdom, might, and riches, and he commends glorying in the knowledge of himself. It also establishes that God's character, specifically his loving kindness, justice, and righteousness, is the content of what we are to know and the reason he is worthy of confidence. The text does not establish that wisdom, strength, or wealth are inherently evil, nor does it require Christians to be foolish, weak, or poor. It also does not promise that those who know God will escape suffering; Jeremiah himself knew God deeply and suffered greatly.
A common misreading treats this verse as a prohibition on competence, ambition, or planning. That is wrong because the command is about glorying, not about possessing or using gifts. Scripture elsewhere commends diligent work, wise planning, and the responsible use of wealth. The error is a category mistake: it confuses the instrument with the foundation. The passage is aimed at the heart's reliance, not at the hands' labour. Reading it as an excuse for laziness or as a licence to despise the gifted reverses what God actually says, since he is the giver of every good gift.

Frequently asked questions
Does Jeremiah 9:23-24 mean Christians should not pursue wisdom or success?
No. The command is against glorying, not against having or using wisdom, strength, or wealth. Scripture elsewhere commends wisdom, diligence, and the wise use of resources. The passage targets the heart's confidence, the thing we treat as our foundation. A believer can pursue excellence in study, work, and leadership while refusing to let any of it become the ground of their security. The question is not whether you have gifts but whether you are leaning on them instead of on God, and that is a matter of the inner life rather than of external achievement.
What does it actually mean to glory in the Lord?
To glory in the Lord is to treat knowing him as your true treasure and to locate your confidence in his character rather than your own credentials. Jeremiah defines it as understanding and knowing God, specifically the God who exercises loving kindness, justice, and righteousness in the earth. Practically, it means your sense of worth, safety, and direction rest on who he is and what he has done. It shows itself in gratitude rather than self-congratulation, in honesty about your limits, and in a life that increasingly cares about the things God says he delights in.
How does 1 Corinthians 1 connect to Jeremiah's command about boasting?
Paul quotes Jeremiah's phrase directly. After observing that not many of the Corinthians were wise, mighty, or noble by worldly standards, he says the only legitimate boast is in the Lord, echoing Jeremiah 9:23-24. In 1 Corinthians 3:18-21 he adds that anyone who thinks he is wise in this world should become a fool so that he may become wise. The point is consistent across both testaments: God resists self-exaltation and gives grace to the humble, and the cross is where that pattern is most clearly displayed.
