The sin of Judah is written with an iron stylusThis phrase indicates the permanence and seriousness of Judah's sin. In ancient times, an iron stylus was used for engraving on hard surfaces, symbolizing that the sin is deeply embedded and not easily erased. This reflects the stubbornness and persistence of Judah's rebellion against God. The use of an iron stylus suggests a deliberate and unrepentant nature of their actions, highlighting the gravity of their idolatry and disobedience.
engraved with a diamond point
The mention of a diamond point emphasizes the hardness and durability of the inscription. Diamonds, being one of the hardest known materials, signify that the sin is not only deeply inscribed but also enduring. This imagery suggests that Judah's sin is not superficial but deeply rooted in their character and culture. The use of such a tool indicates that their iniquity is not easily removed, requiring divine intervention for true cleansing.
on the tablets of their hearts
This phrase suggests that the sin is internalized, affecting the very core of the people's being. The heart, in biblical terms, often represents the center of will, emotion, and intellect. By stating that the sin is on the tablets of their hearts, it implies that the people of Judah have embraced sin at a fundamental level, affecting their thoughts, desires, and decisions. This internalization of sin contrasts with the new covenant promise inJeremiah 31:33, where God writes His law on the hearts of His people.
and on the horns of their altars
The horns of the altar were significant in Israelite worship, symbolizing strength and refuge. By stating that sin is engraved on the horns of their altars, it indicates that even their places of worship are tainted by iniquity. This suggests a corruption of religious practices, where idolatry and false worship have infiltrated what should be sacred. The altars, meant for sacrifices to God, have become places of sin, reflecting a broader spiritual decay. This imagery underscores the need for genuine repentance and a return to true worship.

Teaching Points
The Depth of SinSin is not just a surface issue but is deeply ingrained in the human heart. We must recognize the seriousness of sin in our lives and seek God's forgiveness and cleansing.
The Need for Heart TransformationJust as Judah's sin was engraved on their hearts, we need God to transform our hearts, replacing sin with His law and love.
The Consequences of IdolatryThe reference to the altars reminds us that idolatry corrupts our worship and relationship with God. We must guard against allowing anything to take God's place in our lives.
The Role of RepentanceAcknowledging the depth of our sin should lead us to genuine repentance, turning away from sin and towards God for renewal and restoration.
The Hope of a New CovenantDespite the depth of sin, God offers hope through the new covenant, where He promises to write His laws on our hearts, enabling us to live in obedience to Him.

The sin of Judah is written with an iron stylusJeremiah opens with a mental picture of a scribe taking an iron tool—something sturdy enough to bite into rock—and carving out Judah’s rebellion.
• Iron speaks of strength and durability; this is no pencil mark that time can smudge (cf.Job 19:24, “That they were engraved with an iron tool on lead, or inscribed in rock forever!”).
• The prophet is saying, “Your sin isn’t a momentary lapse; it’s chiseled in.”
• The image echoes the Ten Commandments that were “inscribed by the finger of God” on stone (Exodus 32:16). Judah’s own “stone document” now records the opposite: a covenant of disobedience.
engraved with a diamond pointIron alone is tough, but Jeremiah piles on “diamond” (hardest known substance of his day) to stress permanence.
•Zechariah 7:12 says the people “made their hearts like diamond” to resist the law. Here, diamond cuts them instead—irony at work.
• No ordinary pressure removes a diamond etching; the judgment Judah faces will be equally unerasable (Jeremiah 15:1–2).
on the tablets of their heartsThe real ledger is not external tablets but human hearts.
•Proverbs 3:3 urges God’s people to “write kindness and truth on the tablet of your heart”; Judah has written idolatry instead.
•Jeremiah 31:33 promises a coming day when God Himself will “write My law on their hearts.” This verse shows why that promise is needed: the current “inscription” is sin.
• Paul later contrasts the two conditions—“not on tablets of stone but on tablets of human hearts” written by the Spirit (2 Corinthians 3:3).
and on the horns of their altarsHorns were the most sacred parts of the altar, symbolizing power and refuge (Exodus 27:2;1 Kings 1:50).
• By saying sin is engraved there, Jeremiah shows that even Judah’s worship is polluted; their sacrifices can’t cover what their altars advertise.
•Hosea 8:11 warns, “Judah has multiplied altars for sinning”; the very means of atonement has become a billboard for rebellion.
• When judgment falls, those defiled altars will offer no sanctuary (Amos 3:14).
summaryJeremiah 17:1 paints a stark portrait: Judah’s sin is no surface stain but a deep, diamond-hard engraving—permanent, public, and personal. It resides in their hearts and flaunts itself on their altars, leaving them helpless apart from God’s future promise to rewrite those tablets with His own righteous law.
XVII.
(1)A pen of iron.--i.e.,astylus,or graving tool, as inJob 19:24, chiefly used for engraving in stone or metal. InPsalm 45:1 it seems to have been used of the instrument with which the scribe wrote on his tablets.
With the point of a diamond.--The word expresses the idea of the hardness rather than the brilliancy of the diamond, and is rendered "adamant" inEzekiel 3:9;Zechariah 7:12. (For the diamond as a precious stone a different word is used inExodus 28:18.) Strictly speaking, it was applied only to the diamond-point set in iron used by engravers. Such instruments were known to the Romans (Pliny,Hist. Nat.xxxvii. 15), and may have been in use in Ph?nicia or Palestine. The words describe a note of infamy that could not be erased, and this was stamped in upon the tablets of the heart (comp.2Corinthians 3:3), and blazoned upon the "horns of the altars" of their false worship, or of the true worship of Jehovah which they had polluted and rendered false. The plural "altars" points probably to the former. . . .
Verse 1. -
The sin of Judah, etc. "Judah's sin" is not merely their tendency to sin, but their sinful practices - their idolatry. This is said to be
graven upon the table of their heart, for it is no mere form, but carried on with passionate earnestness, and as indelible as if engraved
with an iron pen. How unlike, however, is this record to that of which the same expression is used in
Job 19:24!
With the point of a diamond; or,
with a point of adamant (harder than flint, as
Ezekiel 3:9 says). Fragments of adamant, says Pliny ('Hist. Nat.,' 37:15), are sought out by engravers and enclosed in iron; they easily overcome every hardness.
Upon the horns of your altars. First of all, what altars are referred to? Those erected for the worship of idols or the two in the temple of Jehovah, which had been defiled by idolatry? And why is the sin of Judah said to be engraved upon the horns of the altars? Probably because the "horns,"
i.e. the projections at the four upper corners (
Exodus 28:2) were smeared with the blood of the victims. The direction in
Exodus 29:12 and
Leviticus 4:7 was doubtless not peculiar to the ritual of the Law.
