1. Context before conclusions
Jeremiah’s ministry speaks into Judah’s covenant unfaithfulness, coming judgment, and the hope of restoration. Jeremiah 30–33 contains sustained promises of restoration amid the book’s warnings and accounts of disaster. Our paragraph must be read in that setting rather than as an isolated promise of personal inspiration. Its named parties are the house of Israel and the house of Judah, and its historical comparison is the exodus covenant.
The passage promises a new covenant while retaining the relational language of belonging to God. It addresses covenant breach, inward instruction, knowledge of the Lord, and forgiveness. The New Testament explicitly quotes it in Hebrews 8 and again uses its language in Hebrews 10. A Christian reading should therefore attend to both the original named recipients and the later explanation of Christ’s ministry. Neither should be erased to make a theological system easier to state.
How to use this guide: Read the whole passage once before looking at the explanations. On a second reading, mark repeated words, contrasts, reasons, and conclusions. The explanations concern the KJV’s English wording and the passage’s argument; they do not claim that every English word position carries a hidden spiritual meaning. No unverified original-language definitions are used.
2. Main study passage
Jeremiah 31:31-34 · KJV
31 Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
3. Trace the passage’s movement
- Verse 31: the Lord announces a new covenant with named recipients.
- Verse 32: the contrast is drawn against the covenant associated with the exodus and its breach.
- Verse 33: God promises inward instruction and covenant belonging.
- Verse 34a: knowledge of the Lord characterizes the promised community.
- Verse 34b: forgiveness and non-remembrance supply the climactic gracious assurance.
4. Detailed exposition
Verse 31 — “Behold” and the God who promises
“Behold” calls attention to a decisive announcement, and “saith the LORD” identifies its authority. The repeated divine first-person actions will govern the paragraph. The people do not announce a self-designed spiritual improvement project; the Lord promises what He will do.
“The days come” points toward a promised future from Jeremiah’s setting. The phrase does not by itself give an exact date or settle every stage of fulfillment. “A new covenant” identifies a fresh covenantal arrangement, but its newness must be explained by the contrasts and promises that follow. “With the house of Israel, and with the house of Judah” names the recipients and holds both houses in view. Do not silently substitute a modern individual or erase either house when paraphrasing the promise.
Verse 32 — The exodus covenant and the reality of breach
“Not according to” introduces a contrast, not a denial that the same God acts. The reference to taking the fathers by the hand to bring them out of Egypt recalls divine initiative and care. The problem is not that God lacked faithfulness; the people broke the covenant.
“Although I was an husband unto them” uses relational imagery for the Lord’s covenant commitment and the seriousness of betrayal. Read the KJV’s wording in its own immediate context. Hebrews 8:9 phrases this portion of the quotation differently; noting that fact is legitimate without altering either KJV passage or claiming they are identical in every English clause. The shared argument concerns a broken earlier covenant and God’s promised new action. A detailed account of textual history would require separate documented study rather than speculation from the English difference alone.
Verse 33a — Law written within
“But this shall be the covenant” moves from negative contrast to positive description. The Lord will put His law in their inward parts and write it in their hearts. The heart in this setting is the inward person, including willing, thinking, and responding; it should not be reduced to an emotional sensation.
Writing within is not permission to elevate private impressions above God’s instruction. The content remains “my law,” and the author of the inward work remains the Lord. Nor does the promise mean that earlier believers never loved God inwardly. Deuteronomy 6:4–9 already commands heart-level love and instruction. The promised change concerns the new covenant’s effective inward reality, not a simplistic story in which every Old Testament person had only external religion.
Verse 33b — “I will be their God”
The relational formula gives the inward work its purpose: a people belonging to God. The promise is not merely that people will become morally impressive in isolation. Instruction, identity, and relationship belong together. God’s repeated “I will” centers the action in His initiative, while “they shall be my people” names its communal outcome.
Continuity and discontinuity must be held together. The same covenant language of God and His people appears earlier in Scripture, while Jeremiah clearly calls this covenant new and contrasts it with the broken arrangement. An advanced interpretation should list what continues and what changes instead of deciding beforehand that new must mean either no continuity or no significant difference. Hebrews 8 develops this contrast through Christ’s better ministry.
Verse 34a — Knowing the Lord and the question of teaching
“They shall teach no more” is qualified by the specific message described: one person telling another to know the Lord. The reason introduced by “for” is that all will know Him, from least to greatest. The passage portrays knowledge of God as characteristic of the promised people, not as a privilege confined to an elite subgroup.
The New Testament still commands teaching and provides teachers, including Matthew 28:20 and Ephesians 4:11–13. Therefore this promise should not be used to abolish all instruction or claim that every present impression is infallible. Traditions differ over how the universal knowledge language relates to present covenant membership and final fulfillment. Some emphasize the regenerate character of the new covenant community; others emphasize a covenant community participating in a promise whose complete realization is still future. Identify the difference without pretending this paragraph alone resolves every dispute about baptism or church membership.
Verse 34b — Forgiveness and non-remembrance
The second “for” supplies the final reason and foundation: God will forgive iniquity and remember sin no more. Forgiveness is not the claim that evil never occurred. “Remember no more” is covenantal language of no longer bringing forgiven sin against the people, not a physiological claim that God loses factual knowledge.
The promise does not identify an independent human payment that compels pardon. Hebrews 10 places the language within its explanation of Christ’s offering. Luke 22:20 connects the new testament with His blood. Read the Christian fulfillment through those explicit connections, not by inventing a sacrificial mechanism from a word’s spelling. The final emphasis is God’s gracious dealing with the covenant-breaking problem introduced in verse 32.
5. Words, phrases, and sentence structure

6. Scripture alongside Scripture
Read the full paragraphs linked here. For each connection, ask what the supporting passage actually establishes and what question it leaves open.
Exodus 24:3-8 · KJV
3 And Moses came and told the people all the words of the LORD, and all the judgments: and all the people answered with one voice, and said, All the words which the LORD hath said will we do.
4 And Moses wrote all the words of the LORD, and rose up early in the morning, and builded an altar under the hill, and twelve pillars, according to the twelve tribes of Israel.
5 And he sent young men of the children of Israel, which offered burnt offerings, and sacrificed peace offerings of oxen unto the LORD.
6 And Moses took half of the blood, and put it in basons; and half of the blood he sprinkled on the altar.
7 And he took the book of the covenant, and read in the audience of the people: and they said, All that the LORD hath said will we do, and be obedient.
8 And Moses took the blood, and sprinkled it on the people, and said, Behold the blood of the covenant, which the LORD hath made with you concerning all these words.
Why this connection matters: The covenant ratification, the people’s stated commitment, and the blood of the covenant clarify the historical background of Jeremiah’s contrast.
Keep the boundary clear: The earlier covenant should not be caricatured as God offering an unloving arrangement; the passage belongs to a story of deliverance and calling.
Hebrews 8:6-13 · KJV
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Why this connection matters: The author explicitly quotes Jeremiah to explain Christ’s better covenant ministry and the change from the former arrangement.
Keep the boundary clear: Note the wording as the KJV presents each passage. Do not silently harmonize the different clause in verse 9 with Jeremiah 31:32.
Luke 22:19-20 · KJV
19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Why this connection matters: Jesus identifies the new testament in His blood in connection with His impending death. This supplies an explicit Christ-centered link.
Keep the boundary clear: Christian traditions differ over the sacramental explanation; the direct connection with His death is shared in the text.
Hebrews 10:14-18 · KJV
14 For by one offering he hath perfected for ever them that are sanctified.
15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
17 And their sins and iniquities will I remember no more.
18 Now where remission of these is, there is no more offering for sin.
Why this connection matters: The promise of inward instruction and forgiven sin is placed alongside Christ’s offering and the conclusion that no further offering for sin is needed.
Keep the boundary clear: Do not turn assurance about His sufficient offering into permission for unrepentant wrongdoing.
7. Difficult questions and interpretive safeguards
Does a Christian reading require erasing Israel and Judah?
No. Jeremiah names both houses, and Hebrews applies the promise in explaining Christ. Christian traditions differ over the full relation between Israel, the church, and future fulfillment. A careful account must do justice to the named recipients, the later quotation, and the wider scriptural argument rather than declaring one of those bodies of evidence irrelevant.
Does “teach no more” make study unnecessary?
No. The statement concerns all knowing the Lord and gives a specific reason. New Testament instructions to teach remain. Distinguish initiating someone into knowledge of God from all the ongoing instruction by which believers grow in understanding and obedience.
Is the heart promise merely a pleasant feeling?
No. God’s law written within concerns the inward life and its response to Him. Feelings may accompany it, but emotional intensity alone does not establish that a particular thought is God’s instruction.
Can forgiveness mean God has forgotten the facts?
The covenantal context supports not holding forgiven sin against His people. Do not build a theory of divine memory from a pastoral idiom while neglecting the actual promise of pardon.

- How does Hebrews 8 guide a Christian reading?
- Explain remember no more in context.
- Name a question these verses do not settle alone.
Open the Scripture-supported answer guide
- Jeremiah 31:31 names the house of Israel and the house of Judah. They locate the promise in the restoration setting and must be considered in any later theological application.
- The people broke it despite the Lord’s leading care and covenant commitment. The text does not blame a lack of divine faithfulness.
- The same Lord, His instruction, and the God-and-people relationship remain. The covenant is new and features inward inscription in contrast with the broken earlier arrangement.
- The content is God’s law and the writer is God; the promise does not make each personal impression an authoritative replacement for His instruction.
- It names the exhortation to know the Lord and explains that all will know Him. The reason and specified message govern its interpretation.
- It explicitly uses Jeremiah’s promise to explain Christ’s better covenant ministry, while preserving a need to read Jeremiah’s named parties and original setting.
- The statement accompanies forgiveness of iniquity. It promises that forgiven sin will not be brought against the covenant people rather than declaring a loss of God’s factual knowledge.
- They do not alone settle every issue about covenant membership, baptism, Israel’s future, or the chronology of fulfillment. Those require wider contextual reasoning rather than an isolated inference.
Use these answers to check your reasoning, not to replace reading the passage. A responsible answer explains why its evidence supports the conclusion and acknowledges where interpretations differ.
Help me to understand what I’ve just read
In plain language
God promises to deal with the problem of a covenant-breaking people through forgiveness and inward renewal. He wants a people who know Him and have His instruction within, not merely people who can display rules outwardly.
Christians read this promise alongside Jesus’ words about the new testament in His blood and Hebrews’ explanation of His offering. The promise invites gratitude and teachability, not the belief that every private feeling is God’s voice.

10. Application, prayer, and further study
Write two lists: the actions God promises and the resulting condition of His people. Let the repeated I will keep the focus on His initiative. Then identify one place where outward conformity needs to become inward, willing obedience.
For a teaching outline, retain the original parties, the contrast with the exodus covenant, the inward promise, and the New Testament use. State which claims are explicit and which belong to a larger theological synthesis.
A prayer: Lord, write Thy truth upon my heart. Deepen my gratitude for forgiveness through Christ, and make my obedience willing and sincere.
This prayer and all explanatory material are original study helps, not additional Scripture.
