Oh that my head were waters, and my eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people!
2Oh that I had in the wilderness a lodging place of wayfaring men, that I might leave my people and go from them! For they are all adulterers, an assembly of treacherous men.
3"They bend their tongue, as their bow, for falsehood. They have grown strong in the land, but not for truth; for they proceed from evil to evil, and they don't know me," says Yahweh.
4"Everyone beware of his neighbor, and don't trust in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.
5Everyone will deceive his neighbor, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves committing iniquity.
6Your habitation is in the middle of deceit. Through deceit, they refuse to know me," says Yahweh.
7Therefore Yahweh of Armies says, "Behold, I will melt them and test them; for how should I deal with the daughter of my people?
8Their tongue is a deadly arrow. It speaks deceit. One speaks peaceably to his neighbor with his mouth, but in his heart, he lays ambush for him.
9Shouldn't I punish them for these things?" says Yahweh. "Shouldn't my soul be avenged on such a nation as this?"
10I will take up a weeping and wailing for the mountains, and a lamentation for the pastures of the wilderness, because they are burned up, so that no one passes through; and they don't hear the voice of the livestock. Both the birds of the sky and the animals have fled. They are gone.
11"I will make Jerusalem heaps, a dwelling place of jackals. I will make the cities of Judah a desolation, without inhabitant."
12Who is the wise man, that may understand this? Who is he to whom the mouth of Yahweh has spoken, that he may declare it? Why has the land perished and is burned up like a wilderness, so that no one passes through?
13Yahweh says, "Because they have forsaken my law which I set before them, and have not obeyed my voice or walked in it,
14but have walked after the stubbornness of their own heart and after the Baals, which their fathers taught them."
15Therefore Yahweh of Armies, the God of Israel, says, "Behold, I will feed them, even this people, with wormwood, and give them poisonous water to drink.
16I will scatter them also among the nations, which neither they nor their fathers have known. I will send the sword after them, until I have consumed them."
17Yahweh of Armies says, "Consider, and call for the mourning women, that they may come. Send for the skillful women, that they may come.
18Let 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.
19For a voice of wailing is heard out of Zion, 'How we are ruined! We are greatly confounded because we have forsaken the land, because they have cast down our dwellings.'"
20Yet hear Yahweh's word, you women, and let your ear receive the word of his mouth. Teach your daughters wailing. Everyone teach her neighbor a lamentation.
21For death has come up into our windows. It has entered into our palaces to cut off the children from outside, and the young men from the streets.
22Speak, "Yahweh says, 'The dead bodies of men will fall as dung on the open field, and as the handful after the harvester. No one will gather them.'"
23Yahweh says, "Don't let the wise man glory in his wisdom. Don't let the mighty man glory in his might. Don't let the rich man glory in his riches.
24But let him who glories glory in this, that he has understanding and knows me, that I am Yahweh who exercises loving kindness, justice, and righteousness in the earth, for I delight in these things," says Yahweh.
25"Behold, the days come," says Yahweh, "that I will punish all those who are circumcised only in their flesh:
26Egypt, Judah, Edom, the children of Ammon, Moab, and all who have the corners of their hair cut off, who dwell in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart."

Summary

Jeremiah 9 opens with the prophet's anguished wish that his eyes were a fountain of tears so he could weep ceaselessly for his people's destruction. God exposes the pervasive deceit saturating Judah — tongues like deadly arrows, neighbors deceiving neighbors — and declares he will refine and scatter them among unknown nations as judgment. The chapter reaches its theological peak in verses 23-24, where God forbids boasting in wisdom, strength, or riches and instead commands people to boast only in knowing him as the God of loving kindness, justice, and righteousness. The closing verses warn that outward circumcision means nothing when the heart remains uncircumcised, a judgment that extends to surrounding nations as well as Judah.

Themes

  • The weeping prophet — Jeremiah's deep anguish over a people he loves but cannot save
  • The destructive power of deceit — tongues as weapons, a society built on lies that makes community impossible
  • True boasting — knowing God and his character (loving kindness, justice, righteousness) as the only worthy ground for confidence
  • Circumcision of the heart — outward religious ritual without inward transformation is worthless before God

Key verses

  • Jer 9:1 — “Oh that my head were waters, and my eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people!”
  • Jer 9:23-24 — “Don't let the wise man glory in his wisdom. Don't let the mighty man glory in his might. Don't let the rich man glory in his riches. But let him who glories glory in this, that he has understanding and knows me, that I am Yahweh who exercises loving kindness, justice, and righteousness in the earth, for I delight in these things.”
  • Jer 9:8 — “Their tongue is a deadly arrow. It speaks deceit. One speaks peaceably to his neighbor with his mouth, but in his heart, he lays ambush for him.”

Context & background

Jeremiah prophesied during the final decades of Judah (modern southern Israel/Palestine) before the Babylonian exile. The social decay he describes — pervasive dishonesty, broken trust between neighbors — reflects the moral collapse of a society that had abandoned the covenant. The "mourning women" (v. 17) were professional female mourners, a well-known institution in the ancient Near East who led communal grief with trained wailing. The nations listed in verses 25-26 — Egypt (modern Egypt), Edom (modern southern Jordan), Ammon (modern central Jordan around Amman), and Moab (modern central Jordan) — all practiced circumcision as a cultural rite, but God warns that physical circumcision without heart devotion is meaningless for any nation, including Judah.

Cross-references

  • 2 Corinthians 10:17 — Paul again cites Jeremiah 9:24 in the context of apostolic boasting
  • Deuteronomy 10:16 — "Circumcise the foreskin of your heart" — the same heart-circumcision theology Jeremiah develops
  • James 3:5-8 — The tongue as a deadly fire, paralleling Jeremiah's description of the tongue as a deadly arrow
  • Romans 2:28-29 — Paul teaches that true circumcision is of the heart, by the Spirit, echoing Jeremiah's warning
