The Book of Jeremiah: The LORD Our Righteousness

Jeremiah 9

Today’s Passage: Jeremiah 9

Here the prophet’s grief spills over the page. Jeremiah wishes his head could become a spring and his eyes a fountain, so that he might weep without ceasing over a people marked for ruin. He looks out on a society where no one can trust his neighbor, where tongues have been trained to lie the way an archer trains his bow, and where the very knowledge of God has been refused. The LORD answers that grief with a solemn word of refining judgment, a lament over the scorched land, and a summons for the professional mourners to come and raise their wail. Then, near the end, after all the sorrow, the chapter climbs to one of the great sentences of the whole Old Testament: a word about what a person may truly boast in, and it turns out to be one thing only, the knowing of God Himself.

As you read, hold this: The only thing worth boasting in is knowing the LORD, whose delight is loving devotion, justice, and righteousness.

Context The world of Jeremiah 9

Jeremiah preached in the last hard years of Judah, when the kingdom was sliding toward the fall of Jerusalem to Babylon in 586 BC. His people had not turned back, and he could see the disaster coming the way a man on a high wall sees a storm still far off, and he wept for what the others would not even believe. This chapter follows straight on from the aching questions of the one before it, and it belongs to that same long lament: a faithful man carrying a message his own neighbors would not hear, grieving a people who would not grieve for themselves.

The great sickness described here is a sickness of the tongue and of the heart. In a covenant society meant to be bound together by truth and steadfast love, everyone had learned instead to deceive, so that a man could no longer trust his own brother or his closest friend. Behind the lying was the deeper thing: they had refused to know the LORD. And so the chapter moves from tears, to a diagnosis of the deceit, to the just sentence of judgment, and finally, mercifully, to the one true ground on which any soul may stand and boast, which is not its own wisdom or strength or wealth, but the knowledge of the God whose delight is loving devotion, justice, and righteousness.

Jeremiah 9:1–2 (BSB)

¹ Oh, that my head were a spring of water, and my eyes a fountain of tears! I would weep day and night over the slain daughter of my people. ² If only I had a traveler’s lodge in the wilderness, I would abandon my people and depart from them, for they are all adulterers, a crowd of faithless people.

This is why we call him the weeping prophet, and here at the door of the chapter we hear his heart break open. He does not want a stronger argument or a louder voice; he wants more tears than one man’s eyes can hold, a whole spring of them, so that he might weep day and night over a people already as good as slain. And in the same breath he confesses the pull to flee, to find some lonely lodge out in the wilderness and simply leave them all behind, so wearying is it to live among faithlessness. Do not miss what this tells us about the true servant of God. He does not preach judgment coldly, from a safe distance. He announces it with a soaked face, torn between grief and the longing to escape, loving the very people whose sin he must expose.

Jeremiah 9:3–6 (BSB)

³ “They bend their tongues like bows; lies prevail over truth in the land. For they proceed from evil to evil, and they do not take Me into account,” declares the LORD. ⁴ “Let everyone guard against his neighbor; do not trust any brother, for every brother deals craftily, and every friend spreads slander. ⁵ Each one betrays his friend; no one tells the truth. They have taught their tongues to lie; they wear themselves out committing iniquity. ⁶ You dwell in the midst of deception; in their deceit they refuse to know Me,” declares the LORD.

Now the LORD Himself names the disease, and it is a disease of the tongue. See the picture He draws: they bend their tongues like bows, taking aim with their words the way an archer takes aim, so that a lie flies straight and true where honesty has been forgotten. It has gone so deep that a man cannot even trust his own brother, for craftiness and slander have become the ordinary speech of the town. And notice the terrible little detail in verse five, that they have taught their tongues to lie and wear themselves out committing iniquity. Sin here is not lazy pleasure; it is exhausting labor, a people worn thin by their own deceit. And under it all lies the root the LORD keeps returning to: in their deceit they refuse to know Me. The broken speech was only the symptom. The refusal of God was the sickness.

Jeremiah 9:7–9 (BSB)

⁷ Therefore this is what the LORD of Hosts says: “Behold, I will refine them and test them, for what else can I do because of the daughter of My people? ⁸ Their tongues are deadly arrows; they speak deception. With his mouth a man speaks peace to his neighbor, but in his heart he sets a trap for him. ⁹ Should I not punish them for these things? declares the LORD. Should I not avenge Myself on such a nation as this?”

Hear the ache even inside the sentence of judgment: what else can I do? The LORD speaks like one who has exhausted every gentler remedy and now must turn to the fire. To refine is what a metalworker does, melting the ore in the furnace so that the dross rises and the pure metal is left, and God will do this hard, purifying work because nothing softer has reached them. He returns to the tongue once more, deadly as arrows, a mouth that says peace while the heart lays a trap, and then He asks a question that is really a solemn declaration of His justice: should I not punish these things? A holy God cannot forever wink at a whole society built on the ambush of the neighbor. His long patience is real, but it is not the same as indifference.

Jeremiah 9:10–11 (BSB)

¹⁰ I will take up a weeping and wailing for the mountains, a dirge over the wilderness pasture, for they have been scorched so no one passes through, and the lowing of cattle is not heard. Both the birds of the air and the beasts have fled; they have gone away. ¹¹ “And I will make Jerusalem a heap of rubble, a haunt for jackals; and I will make the cities of Judah a desolation, without inhabitant.”

And now the weeping widens until it takes in the whole land. It is as if God Himself joins the lament, taking up a dirge over the mountains and pastures gone silent, the fields scorched, the cattle no longer lowing, even the birds and beasts fled from the emptiness. There is something unbearably quiet in this picture, a countryside that has lost its very sounds. Then the sentence falls on the proud city itself: Jerusalem, the joy of the whole earth, made a heap of rubble where jackals prowl, and the towns of Judah left without a single inhabitant. Sin does not stay tidily in the human heart. It spills out and lays waste to everything around it, until the land itself mourns what its people have done.

Jeremiah 9:12–16 (BSB)

¹² Who is the man wise enough to understand this? To whom has the mouth of the LORD spoken, that he may explain it? Why is the land destroyed and scorched like a desert, so no one can pass through it? ¹³ And the LORD answered, “It is because they have forsaken My law, which I set before them; they have not walked in it or obeyed My voice. ¹⁴ Instead, they have followed the stubbornness of their hearts and gone after the Baals, as their fathers taught them.” ¹⁵ Therefore this is what the LORD of Hosts, the God of Israel, says: “Behold, I will feed this people wormwood and give them poisoned water to drink. ¹⁶ I will scatter them among the nations that neither they nor their fathers have known, and I will send a sword after them until I have finished them off.”

A question hangs in the air: who is wise enough to understand why all this has come? And the LORD does not leave it a mystery. He answers plainly, and His answer strips away every excuse. It happened because they forsook His law, would not walk in it, would not obey His voice, and chose instead the stubbornness of their own hearts, running after the Baals just as their fathers had taught them to do. There is the whole tragedy in one sentence: a road handed down from father to son, away from God. And so the just consequence follows, bitter as wormwood, that plant so sharp it became a byword for grief, and the people who would not stay near their God will be scattered among the nations. When a soul insists on its own way long enough, God at last lets it have the harvest of what it planted.

Jeremiah 9:17–22 (BSB)

¹⁷ This is what the LORD of Hosts says: “Take note, and summon the wailing women; send for the most skillful among them. ¹⁸ Let them come quickly and take up a lament over us, that our eyes may overflow with tears, and our eyelids may gush with water. ¹⁹ For the sound of wailing is heard from Zion: ‘How devastated we are! How great is our shame! For we have abandoned the land because our dwellings have been torn down.’” ²⁰ Now, O women, hear the word of the LORD. Open your ears to the word of His mouth. Teach your daughters to wail, and one another to lament. ²¹ For death has climbed in through our windows; it has entered our fortresses to cut off the children from the streets, the young men from the town squares. ²² Declare that this is what the LORD says: “The corpses of men will fall like dung upon the open field, like newly cut grain behind the reaper, with no one to gather it.”

In the ancient world there were women skilled at mourning, called to a funeral to lead the whole village in its grief, and the LORD summons them now because the loss is so great that ordinary weeping will not suffice. Send for the most skillful, He says, and let them teach their daughters and one another to wail, for a whole generation must learn this sorrowful song. Then comes one of the most haunting images in the book: death climbing in through the windows like a thief, slipping past the walls that were meant to keep it out, cutting off the children in the streets and the young men in the squares. No fortress can bar the door against the judgment of God. And the reaping image at the end is deliberately terrible, sheaves of grain left lying with no one to gather them, a harvest of the fallen. We are not meant to hurry past this. We are meant to feel the weight of what it costs to forsake the living God.

Jeremiah 9:23–24 (BSB)

²³ This is what the LORD says: “Let not the wise man boast in his wisdom, nor the strong man in his strength, nor the wealthy man in his riches. ²⁴ But let him who boasts boast in this, that he understands and knows Me, that I am the LORD, who exercises loving devotion, justice and righteousness on the earth—for I delight in these things,” declares the LORD.

And now, out of all that darkness, the chapter climbs to its shining summit, and I would have you slow down and read these two verses more than once. Set against a people who trusted their own cleverness, their own strength, their own full storehouses, and lost it all, the LORD tells us what alone is worth glorying in. Not wisdom, for the wise die like the rest. Not strength, for death climbs through the strongest window. Not riches, for they scatter with the exile. There is one boast that will not fail, and it is this: that a person understands and knows the LORD Himself. And see what He tells us about Himself in the very same breath, for He wants to be known truly. He is the LORD who exercises chesed, pronounced KHEH-sed. Strong's H2617, steadfast love, loyal kindness, covenant faithfulness. This is one of the richest words in the whole Old Testament, and it is a mercy that the LORD chooses it to describe His own delight. It is loyal, covenant love, the steadfast devotion that keeps its promises long after they might have been broken, the tender faithfulness of a God who binds Himself to a people and will not let them go. Translators have reached for many phrases to carry it: lovingkindness, mercy, steadfast love, loving devotion. Notice where it stands in this verse. After nine chapters heavy with judgment, the LORD tells us that what He most delights to exercise on the earth is this, together with justice and righteousness. The God who must refine His people in the fire is, in His very heart, a God whose deepest joy is faithful love. And this is the God the wise man is invited to boast in knowing. , justice, and righteousness on the earth, and, most wonderful of all, He delights in these things. This is the God worth knowing: not a distant power, but One whose very delight is steadfast love and right dealing. To know Him is the only treasure that death cannot climb through a window and steal.

Jeremiah 9:25–26 (BSB)

²⁵ “Behold, the days are coming,” declares the LORD, “when I will punish all who are circumcised only in the flesh— ²⁶ Egypt, Judah, Edom, Ammon, Moab, and all the inhabitants of the desert who clip the hair of their temples. For all these nations are uncircumcised, and the whole house of Israel is uncircumcised in heart.”

The chapter closes with a warning that cuts straight to the heart of true religion. Judah had worn the outward sign of the covenant, circumcision in the flesh, and had leaned on it as though the mark alone could save them. But the LORD sets them in a line with the pagan nations round about, Egypt and Edom and Moab and the rest, and says the day is coming when He will deal with all who are circumcised only in the body. For the whole house of Israel, He says, is uncircumcised in heart. There is the truth that ties this last word back to the great boast of verse twenty-four. It was never the outward badge that God wanted, but a heart that knows Him. A sign on the body that leaves the heart unchanged is no covering at all. What He looks for, then and now, is not the mark of belonging worn on the outside, but the heart laid open and turned toward the God whose delight is loving devotion.

Study notes Going deeper

The great word of this chapter, that the one thing worth boasting in is knowing the LORD, was too precious to be spoken only once. When the Apostle Paul wanted to strip the proud Corinthians of every fleshly boast, he reached back across the centuries and took up Jeremiah’s very words, so that what the weeping prophet cried to a doomed city became the gospel’s own charter for how a redeemed people are to glory.

"Therefore, as it is written: “Let him who boasts boast in the Lord.”" 1 Corinthians 1:31 (BSB)

Hear how the two voices agree across the ages. Human wisdom, human strength, human wealth all fail us in the end, as they failed Judah, and not one of them can be carried through death’s window. But to know the LORD, the God whose delight is loving devotion, justice, and righteousness, and now to know Him in the face of His Son, is a treasure that cannot be taken away. So set your boast where it belongs, not in anything you are or have, but in the God who has made Himself known. Learn the Word, know the One it reveals, and give thanks.
