לֵבָב

לֵבָב (lēbāb) is a Hebrew noun commonly translated heart. Like the closely related H3820 לֵב (lēb), it can refer to the inner person in cognitive, volitional, moral, and emotional dimensions. The two nouns overlap substantially, so a teacher should not invent a rigid distinction between them. At the same time, direct lexical claims for H3824 should be anchored in passages where H3824 actually occurs.

Deuteronomy 6:5 uses H3824 in the command to love the Lord with all one's heart, being, and strength. The word contributes the inner-person dimension of a whole-life covenant command; it does not reduce love to feeling. Deuteronomy 10:16 uses the same noun in the command to circumcise the heart, and Deuteronomy 30:6 promises that the Lord will circumcise the heart so that the people may love him. These direct occurrences create a strong Deuteronomic movement from demand to divine action.

Psalm 24:4 uses H3824 in the description of a pure heart, while Isaiah 6:10 uses it for a heart made insensitive within a commission of judgment. Isaiah 7:2 uses the noun when the hearts of Ahaz and his people shake in fear. These passages demonstrate that H3824 can describe moral integrity, resistant perception, and fearful response. Context, not the lookup number alone, decides which aspect of the inner person is foregrounded.

Jeremiah 17:9 and 31:33, Psalm 51:10, Proverbs 4:23, and Ezekiel 36:26 use H3820 rather than H3824. They can inform a broader biblical theology of the heart, but they should be named as sibling-lexeme parallels rather than direct H3824 witnesses.

The local Hebrew artifact counts about 252 H3824 occurrences. Deuteronomy frequently uses the noun for inward covenant orientation, but its wider occurrences also include thought, courage, fear, integrity, and responsiveness.
