**Pronunciation:** lave (lev); lay-vawb' (levav)
**Part of speech:** masculine nouns; the two forms are functionally synonymous (*levav* is the older / more poetic form; *lev* is the more common prose form).
**Frequency:** ~860 occurrences combined (~600 *lev* + ~260 *levav*), extremely common; distributed throughout the Hebrew Bible, with concentrations in Deuteronomy, Psalms, Proverbs, and the prophets.
**LXX equivalent:** καρδία (*kardia*), direct correspondent. See [G2588 - kardia](/codex/g2588-kardia/).

## Semantic range (Brown-Driver-Briggs)

The Hebrew *lev* / *levav* is *significantly broader* than the modern English "heart." It denotes the **integrating center of the inner person**, encompassing functions modern English distributes across multiple terms (mind, will, conscience, emotions, character, memory).

1. **The physical heart / chest**, the bodily organ; rare; mostly figurative even in literal-anatomy contexts.
2. **The seat of cognition / thought / understanding**, *lev* as *mind*. "What you have *in your heart*" = "what you are thinking" ([Gen 17:17](/codex/genesis-17-17/), Abraham *said in his heart*; the Hebrew idiom for "thought to himself"). Wisdom is "in the heart" ([Prov 2:10](/codex/proverbs-2-10/); 14:33). "A heart to know" ([Deut 29:4](/codex/deuteronomy-29-4/)).
3. **The seat of will / decision / intention**, *lev* as *the choosing self*. "Set your *lev* to" = "decide to" / "commit to." Pharaoh's *hardening of heart* ([Ex 7](/codex/exodus-7/)-14) is a will-and-choice phenomenon, not merely an emotion.
4. **The seat of conscience / moral awareness**, *lev* as the *ethical-self*. David's *lev* "smote him" after the census ([2 Sam 24:10](/codex/2-samuel-24-10/)); his *lev* smote him after cutting Saul's robe ([1 Sam 24:5](/codex/1-samuel-24-5/)).
5. **The seat of memory**, *lev* as where things are *kept* / *stored*. "Lay up in your heart" ([Deut 11:18](/codex/deuteronomy-11-18/)); Mary "kept all these things, pondering them in her *lev* / *kardia*" ([Luke 2:19](/codex/luke-2-19/), [51](/codex/luke-2-51/), Greek-NT activation).
6. **The seat of emotion**, *lev* as feeling: joy, sorrow, fear, love, hatred. The dominant English "heart" sense is here, but it is *one* of many in Hebrew, not the primary one.
7. **The seat of character / disposition**, *lev* as *who one fundamentally is*. "A man after His own *lev*" ([1 Sam 13:14](/codex/1-samuel-13-14/), David). "Pure of *lev*" ([Pss 24:4](/codex/psalms-24-4/); 51:10; 73:1; [Matt 5:8](/codex/matthew-5-8/)).
8. **The "inner person" / "self"**, by extension, *lev* sometimes simply means *one's inmost self*.

## Theological force, the integrating center of the human person

The Hebrew *lev* is the **dominant biblical anthropology term**. Other anthropology-words ([H5315 - nephesh](/codex/h5315-nephesh/), [H7307 - ruach](/codex/h7307-ruach/), [H1320 - basar](/codex/h1320-basar/)) describe humans from particular angles; *lev* describes the *integrating center*, the place where thought, will, emotion, memory, conscience, and character converge and from which action flows.

### Stream 1, The heart's primacy as the moral seat

**[Proverbs 4:23](/codex/proverbs-4-23/)**, "watch over your *lev* with all diligence, for from it flow the springs of life." Wisdom literature consistently treats the *lev* as the *source* of one's life-direction. The deeper-than-actions-seat, the place where the moral self is formed and from which actions emerge.

**[Deuteronomy 6:5](/codex/deuteronomy-6-5/) / the Shema Yisrael**, "you shall love the LORD your God with all your *lev* (*levav*) and with all your *nephesh* and with all your *meod*." The *lev* leads the triplet, the *integrating center* of love-of-God; the others (life-energy, capacity) are subordinate. Jesus quotes this in [Matt 22:37](/codex/matthew-22-37/) / [Mark 12:30](/codex/mark-12-30/) / [Luke 10:27](/codex/luke-10-27/), expanded in the NT to four-fold (heart, soul, *strength* / capacity, *mind* / cognitive function), recognizing that NT Greek's *kardia* needs supplementation by *dianoia* / *ischus* to capture what the OT *lev* held in one term.

### Stream 2, Hardness of heart and circumcision of heart

The OT develops two contrasting heart-conditions: *hardened lev* (the rebellious-unbelieving condition) and *circumcised lev* (the redeemed condition).

**Hardness of heart:**
- [Ex 4:21](/codex/exodus-4-21/); 7:3, 13, 14, 22; 8:15, 19, 32; 9:7, 12, 34, 35; 10:1, 20, 27; 11:10; 14:4, 8, 17, Pharaoh's heart-hardening across the Exodus narrative
- [Deut 29:19](/codex/deuteronomy-29-19/) ("walking in the stubbornness of my *lev*"); [1 Sam 6:6](/codex/1-samuel-6-6/)
- [Ezek 11:19](/codex/ezekiel-11-19/); 36:26, promise of *removing the heart of stone* and giving *a heart of flesh*

**Circumcision of heart:**
- [Deut 10:16](/codex/deuteronomy-10-16/), "circumcise your *lev*"
- [Deut 30:6](/codex/deuteronomy-30-6/), "the LORD your God will circumcise your *lev*", divine action enabling
- [Jer 4:4](/codex/jeremiah-4-4/), "circumcise yourselves to the LORD; remove the foreskin of your *lev*"
- [Rom 2:28-29](/codex/romans-2-28-29/), Paul's NT activation: "true circumcision is of the *kardia*, by the Spirit, not by the letter"

The *lev*-circumcision tradition is the OT-Hebrew prefiguration of NT regeneration. The **[New Covenant](/codex/jeremiah-31-33/)** in [Jeremiah 31:33](/codex/jeremiah-31-33/), "I will put My law within them and on their *lev* I will write it", pairs with [Ezekiel 36:26](/codex/ezekiel-36-26/) ("a new heart will I give you") to anchor the NT doctrine of regeneration / new birth (cf. [John 3:1-15](/codex/john-3-1-15/); [Titus 3:5](/codex/titus-3-5/)).

### Stream 3, Heart as covenantal-personal commitment

To love / serve / fear God *with all your heart* (*be-khol-levavcha*) is to *integrate the whole-self* in covenantal commitment. This is the OT-Hebrew anti-fragmentation doctrine: God is not satisfied with external observance, ritual conformity, or partial allegiance, He demands the *integrating center* of the person.

- [Deut 4:29](/codex/deuteronomy-4-29/); 10:12; 11:13; 13:3; 26:16; 30:2, 6, 10
- [1 Sam 7:3](/codex/1-samuel-7-3/); 12:20, 24
- [1 Kgs 8:23](/codex/1-kings-8-23/), [48](/codex/1-kings-8-48/); [2 Kgs 23:3](/codex/2-kings-23-3/), [25](/codex/2-kings-23-25/)
- [2 Chr 6:14](/codex/2-chronicles-6-14/); 15:12, 15; 22:9; 31:21; 34:31
- [Ps 9:1](/codex/psalms-9-1/); 86:12; 111:1; 119:2, 10, 34, 58, 69, 145
- [Jer 24:7](/codex/jeremiah-24-7/); 29:13
- [Joel 2:12](/codex/joel-2-12/), "return to Me with all your *lev*"

## Patristic / scholarly note

The biblical *lev* / *kardia* is one of the most theologically loaded anthropology terms. **Augustine** (*Confessions* 10.27, "Late have I loved You, O Beauty ever ancient, ever new... You were within me, but I was outside, and there I sought You"), develops the *cor inquietum* (restless heart) tradition that has shaped Christian piety since.

**Calvin** (*Institutes* III.3.5, "the work of repentance"; III.7.1, self-denial), emphasizes the *lev* as the seat of the regenerated will. The Reformed *ordo salutis* (regeneration → faith → repentance → sanctification) is *heart*-centered: the Spirit's work is on the *lev* / *kardia*, not merely on intellect or behavior.

**Pascal** (*Pensées*), "the heart has its reasons that reason knows not of", captures the integrating-center / pre-rational dimension of *lev* / *kardia*. Pascal's tradition has shaped the Christian apologetic engagement with reason-and-affection in modernity.

In modern Reformed scholarship, **Hans Walter Wolff** (*Anthropology of the Old Testament*, 1974), the standard treatment of OT anthropological terminology, with extensive discussion of *lev* / *levav*. **G.K. Beale** (*A New Testament Biblical Theology*, 2011), develops the *new-heart-promise* trajectory from [Jer 31](/codex/jeremiah-31/) / [Ezek 36](/codex/ezekiel-36/) to NT regeneration.

The **regeneration-as-new-heart** tradition is the canonical anchor for the Reformed doctrine of monergistic regeneration. *Lev*-of-stone cannot become *lev*-of-flesh by its own self-effort; only the divine circumcision-of-heart can do that. This *lev*-as-passive-recipient-of-divine-action is one of the strongest OT supports for the Reformed *sola gratia* tradition.
