The Book of Jeremiah

Chapter 17: The Heart Is Deceitful Above All Things

Chapter 17 goes to the root of the human problem: the heart. Judah's sin is 'graven upon the table of their heart,' engraved as if with a diamond point. God draws two portraits, the man who trusts in flesh, cursed and barren 'like the heath in the desert,' and the man who trusts in the LORD, 'blessed... as a tree planted by the waters.' Then comes the great diagnosis: 'The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart.' Jeremiah answers with a prayer every soul can pray, 'Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise.' And the chapter closes with a call to hallow the sabbath, a sign of resting in the God who alone can give the heart its rest.

Setting the Stage

Engraved Sin

Written on the Heart

Judah's sin is cut into the heart with a diamond point, too deep for human effort to erase.

Two Trees

Cursed and Blessed

Trust in flesh makes a barren desert shrub; trust in the LORD makes a tree by the waters.

The Diagnosis

Deceitful Above All Things

The heart is deceitful and desperately wicked; only the LORD who searches it truly knows it.

The Prayer

Heal Me and Save Me

Jeremiah prays for healing and salvation, and God calls His people to rest and hallow His day.

Engraved Sin

Written With a Pen of Iron (Jeremiah 17:1-4)

Judah's sin is not a surface stain but an engraving cut deep into the heart and even onto the horns of her altars, so ingrained that only judgment can answer it.

Jeremiah 17:1-4

Graven Upon the Table of Their Heart

"The sin of Judah is written with a pen of iron, and with the point of a diamond: it is graven upon the table of their heart, and upon the horns of your altars; Whilst their children remember their altars and their groves by the green trees upon the high hills. O my mountain in the field, I will give thy substance and all thy treasures to the spoil, and thy high places for sin, throughout all thy borders. And thou, even thyself, shalt discontinue from thine heritage that I gave thee; and I will cause thee to serve thine enemies in the land which thou knowest not: for ye have kindled a fire in mine anger, which shall burn for ever."

Hebrew Study

"the table of their heart," luach libbam (לוּחַ לִבָּם). A "tablet" of the heart, like a stone tablet on which words are engraved. Sin is cut deep, not written in erasable ink. Paul turns the image to grace: the new covenant writes not sin but Christ's word on "fleshy tables of the heart" (2 Corinthians 3:3).

"the point of a diamond," tsipporen shamir (צִפֹּרֶן שָׁמִיר). The hardest known cutting tool. The engraving of sin is permanent by any human means; nothing softer than a diamond could cut it, and nothing but God's grace can remove it.

Explanation

The chapter opens with a searching image of how deep sin goes. "The sin of Judah is written with a pen of iron, and with the point of a diamond." It is not a passing fault but an engraving, cut permanently "upon the table of their heart, and upon the horns of your altars." Their idolatry had marked even the altars where they falsely worshiped, and it had penetrated the heart itself. So ingrained was it that even "their children remember their altars and their groves", the next generation had absorbed the idolatry as normal. Because the sin is this deep, judgment must be thorough. God will give Judah's "substance and all thy treasures to the spoil," and she will "discontinue from thine heritage", lose the land God gave, and "serve thine enemies in the land which thou knowest not." The reason: "ye have kindled a fire in mine anger, which shall burn for ever." Sin engraved with a diamond point cannot be scrubbed off by human effort; a deeper remedy is needed than anything the sinner can supply.

Gospel Focus

The image of sin "graven upon the table of their heart" reveals why self-reform can never save us. Sin is not a smudge on the surface but an engraving in the heart, cut with a diamond, unerasable by any human tool. This is the same truth as Jeremiah's earlier question, "Can the Ethiopian change his skin?" (Jeremiah 13:23). We cannot un-write what sin has written on us. But the gospel answers this exact problem with a new-covenant miracle. What the old covenant engraved on stone, and what sin engraved on the heart, God promises to replace by writing His own law on the heart, "I will put my law in their inward parts, and write it in their hearts" (Jeremiah 31:33). Paul rejoices that believers are "the epistle of Christ... written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart" (2 Corinthians 3:3). The diamond-cut record of sin is answered by the blood of Christ, which cancels "the handwriting of ordinances that was against us" (Colossians 2:14). What we could never erase, He erases; where sin was engraved, God writes His word by His Spirit. The heart too deep for us to change is not too deep for grace.

Two Trees

Cursed Is the Flesh-Truster, Blessed the God-Truster (Jeremiah 17:5-8)

God sets two portraits side by side: the man who leans on human strength, a barren shrub in a salt desert, and the man who trusts the LORD, a tree by the water that never fears the drought.

Jeremiah 17:5-8

As a Tree Planted by the Waters

"Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD. For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited. Blessed is the man that trusteth in the LORD, and whose hope the LORD is. For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit."

Hebrew Study

"maketh flesh his arm," sam basar zero'o (שָׂם בָּשָׂר זְרֹעוֹ). To make mere "flesh" (frail humanity) one's "arm" (strength). It is the folly of leaning our full weight on what cannot hold, human help, our own ability, apart from God, whose "heart departeth from the LORD."

"the heath in the desert," ar'ar ba-aravah (עַרְעָר בָּעֲרָבָה). A stunted, barren desert shrub, or juniper, scraping by in "a salt land." It "shall not see when good cometh", even when blessing arrives, the flesh-truster cannot receive it, rooted in the wrong soil.

Explanation

God draws two portraits, echoing Psalm 1, and the difference between them is one thing: where a person places their trust. First the curse: "Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD." To lean your full weight on human strength, your own or others', while your heart drifts from God, is to be cursed. Such a person is "like the heath in the desert", a barren shrub in a salt wasteland, who "shall not see when good cometh." Even when blessing comes, he cannot receive it; he is planted in the wrong place. Then the blessing: "Blessed is the man that trusteth in the LORD, and whose hope the LORD is." This person is "as a tree planted by the waters, and that spreadeth out her roots by the river." Because his roots reach the endless supply, drought cannot touch him: "shall not see when heat cometh, but her leaf shall be green... neither shall cease from yielding fruit." Same heat, same year of drought, but opposite outcomes, because one is rooted in flesh and the other in God. Trust determines everything.

Gospel Focus

These verses put the whole of life on one hinge: where do you place your trust? To "make flesh your arm" is to depend ultimately on human resources, your money, your abilities, other people, anything but God, and it leaves the soul as barren as a desert shrub, unable even to receive good when it comes. To "trust in the LORD" is to sink your roots into an inexhaustible river, so that you stay green and fruitful even in drought. This is the difference between a life anchored in Christ and a life anchored in self. Jesus said, "he that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing" (John 15:5), the same tree-and-fruit picture. Notice that the blessed tree still faces "heat" and "the year of drought", trusting God does not exempt us from hardship, but its roots reach water no drought can dry. The circumstances are the same for both trees; the root system is everything. Sink your roots by the river; trust in the LORD and make Him your hope, and you will bear fruit in the very season that withers those who trust in flesh.

The Diagnosis

The Heart Is Deceitful Above All Things (Jeremiah 17:9-13)

God gives the definitive diagnosis of the human heart, deceitful and desperately sick beyond our own knowing, and declares that He alone searches it and repays each one, the fountain of living waters whom to forsake is shame.

Jeremiah 17:9-13

I the LORD Search the Heart

"The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings. As the partridge sitteth on eggs, and hatcheth them not; so he that getteth riches, and not by right, shall leave them in the midst of his days, and at his end shall be a fool. A glorious high throne from the beginning is the place of our sanctuary. O LORD, the hope of Israel, all that forsake thee shall be ashamed, and they that depart from me shall be written in the earth, because they have forsaken the LORD, the fountain of living waters."

Hebrew Study

"deceitful above all things," aqov ha-lev mi-kol (עָקֹב הַלֵּב מִכֹּל). Aqov is related to the name Jacob ("supplanter, deceiver"); the heart is crooked, twisting, deceptive beyond anything else. "Desperately wicked," anush, means incurably sick. The heart is both dishonest and diseased past self-cure.

"I try the reins," bochen kelayot (בֹּחֵן כְּלָיוֹת). God tests the "kidneys," the innermost self. Only the God who searches the heart truly knows it. Revelation applies this to the risen Christ, "I am he which searcheth the reins and hearts" (Revelation 2:23), the divine prerogative belonging to Jesus.

Explanation

Verse 9 is one of the most important statements about human nature in the Bible: "The heart is deceitful above all things, and desperately wicked: who can know it?" The heart, the seat of will and desire, is not basically good but deceptive, twisting, and incurably sick. And most dangerously, it deceives its own owner, "who can know it?" We cannot even accurately read ourselves; the heart hides its true condition from us. But there is One who sees clearly: "I the LORD search the heart, I try the reins, even to give every man according to his ways." God knows what we cannot, and He judges truly. Verse 11 gives a proverb of futility: the man who "getteth riches, and not by right" is like a partridge sitting on eggs that never hatch, he will "leave them in the midst of his days, and at his end shall be a fool." Ill-gotten gain is a nest that comes to nothing. Then the prophet lifts his eyes to God, "A glorious high throne... is the place of our sanctuary," and confesses the truth that undergirds it all: "all that forsake thee shall be ashamed... because they have forsaken the LORD, the fountain of living waters." The deceitful heart's fatal choice is to abandon the Fountain.

Gospel Focus

"The heart is deceitful above all things, and desperately wicked." This verse demolishes every gospel of self-improvement and every notion that people are basically good. The problem is not merely bad choices but a heart that is dishonest and incurably diseased, so deceptive it fools even us. Jesus taught the same, that defilement comes "from within, out of the heart of men," listing evil thoughts, murders, and pride (Mark 7:21-23). This is why we cannot save ourselves: we cannot even accurately diagnose ourselves. But the same God who alone "searches the heart" is the God who alone can heal it. What the heart cannot cure, God re-creates: "A new heart also will I give you... and I will take away the stony heart" (Ezekiel 36:26), the very promise fulfilled in the new birth. And that God who "searcheth the reins and hearts" is revealed in Revelation 2:23 to be the risen Christ, the divine prerogative belongs to Jesus. The right response to a deceitful heart is not self-confidence but the prayer of the next verses, and of the psalmist, "Search me, O God, and know my heart" (Psalm 139:23). Do not trust your own heart, "he that trusteth in his own heart is a fool" (Proverbs 28:26). Bring it to the God who searches and heals it, and receive the new heart only He can give.

The Prayer

Heal Me, and I Shall Be Healed (Jeremiah 17:14-18)

Facing mockers who demand that his prophecies come true, Jeremiah turns to God with a prayer of total dependence for healing, salvation, and vindication, resting on the LORD as his hope in the day of evil.

Jeremiah 17:14-18

Thou Art My Hope in the Day of Evil

"Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise. Behold, they say unto me, Where is the word of the LORD? let it come now. As for me, I have not hastened from being a pastor to follow thee: neither have I desired the woeful day; thou knowest: that which came out of my lips was right before thee. Be not a terror unto me: thou art my hope in the day of evil. Let them be confounded that persecute me, but let not me be confounded: let them be dismayed, but let not me be dismayed: bring upon them the day of evil, and destroy them with double destruction."

Hebrew Study

"Heal me... and I shall be healed," refa'eni... ve-erafe (רְפָאֵנִי... וְאֵרָפֵא). The grammar itself confesses total dependence: if You heal, I am healed; if not, there is no other cure. Real healing and salvation come only from God, and where He acts, the result is certain, "for thou art my praise."

"thou art my praise," tehillati attah (תְּהִלָּתִי אָתָּה). God is the object and reason of Jeremiah's praise, his boast and glory. In a world of mockery, God Himself, not his reputation or success, is what the prophet celebrates and clings to.

Explanation

Having exposed the incurable heart, Jeremiah prays a prayer that fits that diagnosis perfectly: "Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise." The wording is a confession of total dependence, only God can heal, only God can save, and where He acts, the outcome is sure. Jeremiah then brings his real pressure to God. The mockers taunt him, "Where is the word of the LORD? let it come now", jeering because his prophecies of judgment had not yet fallen. He defends his integrity: "I have not hastened from being a pastor to follow thee; neither have I desired the woeful day", he had not gleefully wished disaster on his people, and his words were "right before thee." He asks God, "Be not a terror unto me: thou art my hope in the day of evil", let the God he serves be his refuge, not his dread. And, in the raw honesty of his laments, he asks God to vindicate him against his persecutors. Above all, the prayer rests everything on God: God is his healing, his salvation, his praise, his hope. In the day of evil, the prophet's only security is the LORD Himself.

Gospel Focus

"Heal me, O LORD, and I shall be healed; save me, and I shall be saved." This is the perfect prayer for a soul that has grasped the diagnosis of verse 9. If the heart is deceitful and desperately wicked, then healing and salvation cannot come from within; they must come from God, and where He works, they are certain, "and I shall be healed... and I shall be saved." The gospel answers this prayer in Christ, "with his stripes we are healed" (Isaiah 53:5), and "neither is there salvation in any other" (Acts 4:12). The very structure of the prayer, "Heal me... save me," is the cry of grace: not "help me heal myself" but "You heal me." And notice where Jeremiah finds his security under mockery and pressure, "thou art my hope in the day of evil." When our reputation is attacked and our faithfulness questioned, the answer is not to lean on our own defense but to make God our hope and praise. The deceitful heart the chapter exposed is met, in the same chapter, by the God who heals it. Bring your incurable heart to the only Physician who can cure it, and pray Jeremiah's prayer with confidence: heal me, and I shall be healed; save me, and I shall be saved, for You are my praise.

The Rest

Hallow the Sabbath Day (Jeremiah 17:19-27)

God sends Jeremiah to the city gates with a call to honor the sabbath, holding out life and continuance for obedience and fire for refusal, a summons to rest in God rather than in ceaseless self-effort.

Jeremiah 17:19-27

Hallow Ye the Sabbath Day

"Thus said the LORD unto me; Go and stand in the gate of the children of the people, whereby the kings of Judah come in, and by the which they go out, and in all the gates of Jerusalem; And say unto them, Hear ye the word of the LORD, ye kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates: Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem; Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers. But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction. And it shall come to pass, if ye diligently hearken unto me, saith the LORD, to bring in no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein; Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes, the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever. And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and meat offerings, and incense, and bringing sacrifices of praise, unto the house of the LORD. But if ye will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched."

Hebrew Study

"hallow ye the sabbath," qiddashtem (קִדַּשְׁתֶּם). To set apart as holy, to keep the day distinct and sacred. The sabbath was a sign of the covenant (Exodus 31:13), a weekly confession that life rests on God's provision, not endless human labor. To profane it was to declare independence from God.

"bear no burden," lo tissu massa (לֹא תִשְׂאוּ מַשָּׂא). Carrying loads for trade on the sabbath turned the holy day into a business day. The command exposed where the heart's trust really lay, in God's provision, or in ceaseless getting.

Explanation

The chapter ends with a specific, practical test: the sabbath. God sends Jeremiah to "the gate of the children of the people," the busiest gates of Jerusalem, to call kings and commoners alike to "bear no burden on the sabbath day... but hallow ye the sabbath day, as I commanded your fathers." The issue was not merely a rule but the heart behind it: keeping the sabbath was a weekly act of trust, resting from labor because life depends on God, not on endless work and trade. Judah had ignored it, "they obeyed not... but made their neck stiff." God then holds out a clear choice with real consequences. If they will "diligently hearken" and hallow the sabbath, the city will flourish, kings on David's throne, worshipers streaming in with "sacrifices of praise," and "this city shall remain for ever." But if they refuse, "then will I kindle a fire in the gates thereof... and it shall not be quenched." The sabbath was a small, concrete point on which the whole disposition of the heart was tested: would they trust and obey God even in this, or insist on their own way?

Gospel Focus

The sabbath was always more than a rule; it was a sign pointing to rest in God. To stop working one day in seven was a weekly confession that our life and provision rest on the LORD, not on our own ceaseless effort, the same trust the chapter has been urging all along ("blessed is the man that trusteth in the LORD"). And the New Testament reveals what the sabbath foreshadowed: the true rest found in Christ. Jesus said, "Come unto me, all ye that labour and are heavy laden, and I will give you rest" (Matthew 11:28), and Hebrews teaches that "there remaineth therefore a rest to the people of God," entered "by faith," ceasing from our own works as God did from His (Hebrews 4:9-10). The heart that trusts in flesh can never rest; it must keep working, grasping, "bearing burdens," because it leans on itself. The heart that trusts in the LORD can lay the burden down. This is the deepest gospel meaning of the sabbath call: stop striving to save and secure yourself, and rest in the finished work of Christ. The deceitful, restless heart of verse 9 finds its cure not in more labor but in the rest God gives. Cease from your own works; trust the LORD; and enter His rest.

Chapter 17 in Review

Jeremiah 17 diagnoses the human heart and prescribes its cure. Judah's sin is "graven upon the table of their heart" with a diamond point, too deep to erase by human effort. God contrasts two trees: the flesh-truster, cursed and barren "like the heath in the desert," and the God-truster, "blessed... as a tree planted by the waters" that never fears the drought. Then comes the great diagnosis, "The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart." Jeremiah answers with the perfect prayer, "Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise," and rests on God as "my hope in the day of evil." And the chapter closes with the sabbath call, a sign of trusting and resting in God rather than in endless self-effort.

For the Apostolic reader this chapter drives us straight to Christ. The sin engraved on the heart, which no self-help can erase, is answered by the new covenant that writes God's law on the heart and by the blood that cancels the handwriting against us. The deceitful, "desperately wicked" heart that we cannot even know is searched and healed only by the God who gives a new heart, and who, as the risen Christ, "searcheth the reins and hearts." The prayer "heal me... save me" is answered in the One by "whose stripes we are healed." And the sabbath points to the rest Jesus gives to all who "labour and are heavy laden." Do not trust your own heart or make flesh your arm. Sink your roots by the river, bring your incurable heart to the Physician, and cease from your own works to rest in Christ.

Key Takeaways
  • Sin is engraved deep on the heart; self-reform cannot erase it, but the new covenant re-writes it (17:1; Jeremiah 31:33; 2 Corinthians 3:3; Colossians 2:14).
  • Trust in flesh makes a barren shrub; trust in the LORD makes a fruitful tree by the river (17:5-8; Psalm 1; John 15:5).
  • "The heart is deceitful above all things, and desperately wicked": we cannot even know ourselves (17:9; Mark 7:21-23; Proverbs 28:26).
  • Only God searches and heals the heart, a prerogative belonging to the risen Christ (17:10; Ezekiel 36:26; Revelation 2:23).
  • The prayer of grace: "Heal me... and I shall be healed; save me... and I shall be saved" (17:14; Isaiah 53:5; Acts 4:12).
  • The sabbath signs the rest found in Christ; cease from your own works and trust Him (17:22; Matthew 11:28; Hebrews 4:9-10).

Questions for Reflection

  • Where are you tempted to "make flesh your arm" rather than trust the LORD? Which tree are you living as?
  • Do you believe your own heart is "deceitful above all things," or do you trust it too readily?
  • Can you pray Jeremiah's prayer honestly: "Heal me... save me," depending wholly on God?
  • The sabbath calls us to rest in God. Where are you still "bearing burdens," striving to secure yourself instead of resting in Christ?
