Verse-by-Verse Commentary
The Book of Jeremiah
Chapter 9: Let Him That Glorieth Glory in This
Jeremiah is called the weeping prophet, and this chapter shows why: 'Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people!' He grieves a society where truth has collapsed, where neighbors deceive neighbors and every tongue is 'bent like a bow for lies.' God announces the melting fire of judgment and calls for the mourning women to raise a wail, for 'death is come up into our windows.' And at the heart of it all stands one of the most important verses in the Bible about what truly matters: 'Let not the wise man glory in his wisdom... but let him that glorieth glory in this, that he understandeth and knoweth me.'

Setting the Stage
A Fountain of Tears
The weeping prophet grieves a people of lies, where no one is valiant for the truth.
I Will Melt and Try Them
God brings the refining fire and reveals why the land perishes: they forsook His law.
Death in the Windows
Call the mourning women; death climbs into the palaces to cut off the children and young men.
That He Knoweth Me
Not wisdom, might, or riches, but knowing God is the one thing worth glorying in.
Oh That My Head Were Waters (Jeremiah 9:1-6)
The prophet longs to weep day and night, and even to flee from a people whose whole society has been built on lies, deceit, and a settled refusal to know God.
Through Deceit They Refuse to Know Me
"Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people! Oh that I had in the wilderness a lodging place of wayfaring men; that I might leave my people, and go from them! for they be all adulterers, an assembly of treacherous men. And they bend their tongues like their bow for lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the LORD. Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders. And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity. Thine habitation is in the midst of deceit; through deceit they refuse to know me, saith the LORD."
Hebrew Study
"a fountain of tears," meqor dim'ah (מְקוֹר דִּמְעָה). A spring of tears, the same word meqor used for the "fountain of living waters" (2:13). The prophet wishes his eyes could pour endlessly. His grief is not weakness but a share in the very heart of God for a perishing people.
"not valiant for the truth," lo le-emunah gavru (לֹא לֶאֱמוּנָה גָבְרוּ). They were "not strong/brave for faithfulness." They had courage for evil but no courage for the truth. Standing for truth requires valor, and it was exactly the courage they lacked.
Explanation
This is the passage that earned Jeremiah his title, the weeping prophet. "Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people!" He longs to cry an endless flood over his doomed nation. And yet he is so grieved by their sin that he also wishes he could "leave my people, and go from them," to escape into a desert inn, because "they be all adulterers, an assembly of treacherous men." Jeremiah loves them enough to weep and is wounded enough to want to flee, the double ache of a faithful heart. He describes a society rotted through with dishonesty. They "bend their tongues like their bow for lies," they are "not valiant for the truth," they "proceed from evil to evil." Trust has collapsed completely: "trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders." They have "taught their tongue to speak lies" and even "weary themselves to commit iniquity", they work hard at sin. And the root of it all is named twice: "they know not me... through deceit they refuse to know me." The lying life is finally a refusal to know the God of truth.
Gospel Focus
Jeremiah's tears are a shadow of the tears of Christ. When Jesus "beheld the city, and wept over it" (Luke 19:41), He was the greater Jeremiah, God Himself weeping over a people who would not know Him. The heart that grieves over sinners rather than despising them is the heart of God, "God our Saviour; Who will have all men to be saved" (1 Timothy 2:3-4). Notice too that the deepest problem in this society of lies is spiritual: "through deceit they refuse to know me." Dishonesty is not merely a social failing; it is a flight from the God of truth, for a life built on lies cannot bear the light of the One who is Truth. Jesus said the devil "is a liar, and the father of it" (John 8:44), and that He Himself is "the truth" (John 14:6). To walk in deceit is to walk away from God; to come to the truth is to come to Him. And the call to be "valiant for the truth" still stands. In every age it takes courage to be honest, to stand for what is true when lies are easier and safer. Weep with the weeping prophet over a world of deceit, and be one who is valiant for the truth, because you know the God of truth.
I Will Melt Them and Try Them (Jeremiah 9:7-16)
God announces the refining fire of judgment on a people whose tongues are deadly arrows, and explains plainly why the land will be laid waste: they forsook His law and followed the idols of their fathers.
Because They Have Forsaken My Law
"Therefore thus saith the LORD of hosts, Behold, I will melt them, and try them; for how shall I do for the daughter of my people? Their tongue is as an arrow shot out; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait. Shall I not visit them for these things? saith the LORD: shall not my soul be avenged on such a nation as this? For the mountains will I take up a weeping and wailing, and for the habitations of the wilderness a lamentation, because they are burned up, so that none can pass through them; neither can men hear the voice of the cattle; both the fowl of the heavens and the beast are fled; they are gone. And I will make Jerusalem heaps, and a den of dragons; and I will make the cities of Judah desolate, without an inhabitant. Who is the wise man, that may understand this? and who is he to whom the mouth of the LORD hath spoken, that he may declare it, for what the land perisheth and is burned up like a wilderness, that none passeth through? And the LORD saith, Because they have forsaken my law which I set before them, and have not obeyed my voice, neither walked therein; But have walked after the imagination of their own heart, and after Baalim, which their fathers taught them: Therefore thus saith the LORD of hosts, the God of Israel; Behold, I will feed them, even this people, with wormwood, and give them water of gall to drink. I will scatter them also among the heathen, whom neither they nor their fathers have known: and I will send a sword after them, till I have consumed them."
Hebrew Study
"melt them, and try them," tsorfam u-vachantim (צוֹרְפָם וּבְחַנְתִּים). Refining and testing metal by fire. God's judgment is not merely punitive but purifying, meant to burn away the dross. Yet His grief shows in the aside, "how shall I do for the daughter of my people?", the Refiner's heart aches even as the fire is lit.
"wormwood," la'anah (לַעֲנָה). A bitter, poisonous plant. Paired with "water of gall," it pictures the bitter cup the people must drink. What began as sweet-seeming sin ends in bitterness, "her end is bitter as wormwood" (Proverbs 5:4).
Explanation
God responds to the deceit with refining judgment: "Behold, I will melt them, and try them." Even here His heart breaks, "how shall I do for the daughter of my people?", the pain of a Father who must discipline a beloved child. He describes their weaponized speech: "their tongue is as an arrow shot out," deadly and deceptive, speaking "peaceably" while the "heart... layeth his wait." So the just question returns, "Shall I not visit them for these things?" God Himself takes up a lamentation over the coming desolation of the land, silent of cattle, emptied of birds and beasts, Jerusalem reduced to "heaps, and a den of dragons." Then comes the crucial question: "Who is the wise man, that may understand... for what the land perisheth?" And God gives the plain answer, the key to the whole tragedy: "Because they have forsaken my law... and have not obeyed my voice... But have walked after the imagination of their own heart, and after Baalim." The reason for the ruin is not mysterious. They abandoned God's word for their own imagination and inherited idols. So they must drink "wormwood" and "water of gall," and be "scattered among the heathen." The bitter harvest follows the forsaken law.
Gospel Focus
Verse 12 asks who is wise enough to understand why the land perishes, and verse 13 answers with startling clarity: "Because they have forsaken my law." God is never arbitrary in judgment; there is always a moral cause, and here it is plainly stated. This cuts against the human tendency to blame God, or fate, or circumstance for the ruin our own choices produce. The wise understand that sin has consequences and that forsaking God's word is the root of the wreckage. But notice the refining purpose behind the fire, "I will melt them, and try them." God's aim in judgment is not destruction but purification, to burn away the dross so that what is precious remains. And notice again the Refiner's grief, "how shall I do for the daughter of my people?" This is not a God who delights to punish but One who agonizes even as He must act, the same heart that would one day drink the "wormwood" and "gall" Himself. At the cross Jesus was offered gall and drank the bitter cup of judgment in our place (Matthew 27:34), so that we might drink instead "the cup of blessing" (1 Corinthians 10:16). The wise man understands the cause of ruin, forsaking God, and runs to the Christ who bore the bitterness for us.
Death Is Come Up Into Our Windows (Jeremiah 9:17-22)
God summons the professional mourning women to teach the whole land to wail, for death itself is climbing through the windows into the houses, cutting off children and young men alike.
Teach Your Daughters Wailing
"Thus saith the LORD of hosts, Consider ye, and call for the mourning women, that they may come; and send for cunning women, that they may come: And let them make haste, and take up a wailing for us, that our eyes may run down with tears, and our eyelids gush out with waters. For a voice of wailing is heard out of Zion, How are we spoiled! we are greatly confounded, because we have forsaken the land, because our dwellings have cast us out. Yet hear the word of the LORD, O ye women, and let your ear receive the word of his mouth, and teach your daughters wailing, and every one her neighbour lamentation. For death is come up into our windows, and is entered into our palaces, to cut off the children from without, and the young men from the streets. Speak, Thus saith the LORD, Even the carcases of men shall fall as dung upon the open field, and as the handful after the harvestman, and none shall gather them."
Hebrew Study
"mourning women," meqonenot (מְקוֹנְנוֹת). Professional mourners, skilled women hired to lead public lamentation with wailing and dirges. The scene is so catastrophic that ordinary grief is not enough; the experts in sorrow must be called, and even they must teach their daughters new laments.
"death is come up into our windows," alah mavet be-challoneinu (עָלָה מָוֶת בְּחַלּוֹנֵינוּ). Death personified as a thief or predator climbing in through the windows, past every lock and wall. No defense keeps it out; it reaches even the children in the courtyard and the young men in the street.
Explanation
The coming catastrophe calls for organized, public grief. God says, "call for the mourning women", the professional wailers, "and send for cunning women" (skilled in lament), "that they may come." The disaster is so great that these experts must "make haste" and lead the whole community in weeping "that our eyes may run down with tears." A cry already rises "out of Zion": "How are we spoiled! we are greatly confounded... our dwellings have cast us out." So terrible is the coming loss that the mourning women must "teach your daughters wailing", a whole generation trained in grief, because there will be so much to mourn. And the reason is stated in a chilling image: "death is come up into our windows, and is entered into our palaces, to cut off the children from without, and the young men from the streets." Death climbs past every defense to take the young. The dead will be so many that "the carcases of men shall fall as dung upon the open field... and none shall gather them", no one left even to bury them. It is a portrait of total, overwhelming loss.
Gospel Focus
"Death is come up into our windows." This haunting image captures the reach of death into every home, past every wall we build against it. Death is no respecter of persons or defenses; it takes children and young men, not only the old. This is the universal human predicament that only the gospel answers, "it is appointed unto men once to die, but after this the judgment" (Hebrews 9:27), "for that all have sinned" (Romans 5:12). No fortress keeps death out. But there is One who climbed down into death itself to defeat it from within. Jesus entered the very grave and "abolished death, and hath brought life and immortality to light through the gospel" (2 Timothy 1:10). Because He rose, the believer can say, "O death, where is thy sting?" (1 Corinthians 15:55). The death that climbs through the windows of Jeremiah 9 has been robbed of its final victory by the empty tomb. The mourning women teach their daughters to wail; the gospel teaches us a better song, for those who die in Christ do not perish but "sleep in Jesus" and will rise (1 Thessalonians 4:14). Death has come into our windows, but Christ has come into our death, and turned it into a door.
Let Him Glory in Knowing Me (Jeremiah 9:23-26)
Above wisdom, might, and riches, God names the one thing truly worth glorying in, to know Him, and warns that an uncircumcised heart, not an uncircumcised body, is what condemns.
That He Understandeth and Knoweth Me
"Thus saith the LORD, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches: But let him that glorieth glory in this, that he understandeth and knoweth me, that I am the LORD which exercise lovingkindness, judgment, and righteousness, in the earth: for in these things I delight, saith the LORD. Behold, the days come, saith the LORD, that I will punish all them which are circumcised with the uncircumcised; Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that are in the utmost corners, that dwell in the wilderness: for all these nations are uncircumcised, and all the house of Israel are uncircumcised in the heart."
Hebrew Study
"understandeth and knoweth me," haskel ve-yadoa oti (הַשְׂכֵּל וְיָדֹעַ אוֹתִי). To have insight into and intimately know God. Yada is relational knowing, not mere information. The one boast God permits is a personal, saving knowledge of Him, which is the very definition of eternal life (John 17:3).
"uncircumcised in the heart," arlei lev (עַרְלֵי לֵב). The outward covenant sign is nothing without the inward reality. Judah had the mark in the flesh but not in the heart, so God counts her with the pagans. What matters is a heart circumcised to Him (Deuteronomy 10:16; Romans 2:29).
Explanation
After all the grief and judgment, God names what truly matters, and it reorders everything the world values. "Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches." The three great human boasts, intellect, power, and wealth, are stripped of their claim to be ultimate. Instead, "let him that glorieth glory in this, that he understandeth and knoweth me." The one thing worth boasting in is to know God, not to know about Him but to know Him personally. And God tells us what He is like, what those who know Him come to treasure: "I am the LORD which exercise lovingkindness, judgment, and righteousness, in the earth: for in these things I delight." God delights in steadfast love, justice, and righteousness, and those who know Him come to delight in them too. Finally, God warns that outward religion saves no one: He "will punish all them which are circumcised with the uncircumcised," because "all the house of Israel are uncircumcised in the heart." Having the covenant sign in the body meant nothing while the heart remained unchanged.
Gospel Focus
Verses 23-24 are quoted twice by Paul, who distills them into a single phrase: "He that glorieth, let him glory in the Lord" (1 Corinthians 1:31; 2 Corinthians 10:17). This is the great reordering of the gospel. The world glories in wisdom, might, and riches, the very things it chases and worships, but God says the only worthy boast is to know Him. And Jesus defined eternal life in exactly these terms: "this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent" (John 17:3). To know God is not a bonus added to a successful life; it is the one thing that makes any life truly rich. Paul, who had the wisdom, status, and pedigree the world prizes, counted it all "loss for the excellency of the knowledge of Christ Jesus my Lord" (Philippians 3:8). And the closing warning about the "uncircumcised in the heart" reaches its fulfillment in the New Testament truth that "circumcision is that of the heart, in the spirit" (Romans 2:29), a heart made new by God, not a mark in the flesh. The question this chapter finally presses is the deepest of all: not what you have achieved, possess, or command, but do you know God? Glory in that, and in nothing else.
Chapter 9 in Review
Jeremiah 9 is the weeping prophet's lament and the LORD's own grief over a society built on lies. Jeremiah longs for "a fountain of tears" to weep over a people who "bend their tongues like their bow for lies" and "through deceit... refuse to know me." God announces the refining fire, even as His heart aches, "how shall I do for the daughter of my people?", and answers plainly why the land perishes: "Because they have forsaken my law." He calls the mourning women to teach a generation to wail, for "death is come up into our windows." And then, above all the sorrow, He names the one thing worth living for: "let him that glorieth glory in this, that he understandeth and knoweth me," warning that a heart "uncircumcised" makes even the covenant sign worthless.
For the Apostolic reader this chapter both weeps and points to Christ. Jeremiah's tears foreshadow Jesus weeping over Jerusalem, the heart of God for the lost. The bitter cup of "wormwood" and "gall" was drunk by Christ so that we might drink the cup of blessing. The death that climbs through every window was invaded and defeated by the One who entered the grave and rose. And the great word of verses 23-24, which Paul makes "He that glorieth, let him glory in the Lord," sets the whole of life in order: not wisdom, might, or riches, but knowing God is our one boast, and to know Him is eternal life. Do not glory in what the world glories in. Weep over sin, run from deceit, and glory in this alone, that you know the LORD who delights in lovingkindness, judgment, and righteousness, made known to us in Jesus Christ.
- The weeping prophet shares God's heart for the lost, foreshadowing Jesus weeping over Jerusalem (9:1; Luke 19:41).
- A life of deceit is finally a refusal to know the God of truth; be "valiant for the truth" (9:3, 6; John 14:6).
- Judgment is never arbitrary: "Because they have forsaken my law" (9:13); the fire aims to refine (9:7).
- Death reaches into every home, but Christ entered death and abolished it (9:21; 2 Timothy 1:10; 1 Corinthians 15:55).
- The one worthy boast is to know God: "let him that glorieth glory in this, that he... knoweth me" (9:23-24; 1 Corinthians 1:31; John 17:3).
- Outward religion cannot save an "uncircumcised" heart; God wants the heart made new (9:25-26; Romans 2:29).
Questions for Reflection
- Does the sin around you move you to tears and prayer, as it moved Jeremiah, or only to disgust?
- Are you "valiant for the truth," willing to be honest even when lies are easier?
- The world glories in wisdom, might, and riches. What do you most glory in, and does it need reordering?
- Do you merely know about God, or do you truly know Him, which is eternal life?
