כָּזָב
falsehood; literally (untruth) or figuratively (idol)
Definition
The Hebrew noun כָּזָב (kâzâb) primarily denotes 'falsehood' or 'a lie,' encompassing both concrete verbal deceit and abstract falsehood. In its literal sense, it refers to an untrue statement, as when Samson deceives Delilah with a 'lie' (Judges 16:10, 13). Figuratively, it extends to describe idols and false gods as embodiments of deception and unreality, contrasting with the truth of Yahweh (Psalm 40:4, Jeremiah 10:14). The word thus captures the spectrum from a simple untruth to the profound spiritual deception of idolatry.
Biblical Usage
כָּזָב appears 30 times, predominantly in the poetic and wisdom literature (Psalms, Proverbs, Jeremiah). It is used to describe deceptive speech (Psalm 5:6), the inherent falsehood of the wicked (Psalm 58:3), and the unreliable nature of human beings (Psalm 62:9). A significant pattern is its use in contrast to terms for truth, faithfulness, and salvation, highlighting the antithesis between divine reality and human deceit. For example, Psalm 40:4 contrasts trusting in lies with trusting in the LORD.
Etymology
Derived from the root verb כָּזַב (kāzab, H3576), meaning 'to lie, to be false, to fail.' This root conveys the idea of proving deceptive or disappointing, such as a stream that dries up (Job 6:15-20 uses a related noun). Thus, the noun כָּזָב carries the core sense of that which is deceptive, unreliable, or ultimately unfulfilling.
Semantic Range
This word is theologically significant as it defines a core characteristic of evil opposed to God's nature of truth. It is associated with false prophecy, idolatry, and the deceitful human heart. Understanding כָּזָב enriches reading by clarifying that biblical 'falsehood' is not merely incorrect information but a fundamental spiritual posture of rebellion and unreliability, standing in opposition to 'emet (truth, faithfulness). It is one of the 'six things that the LORD hates' in Proverbs 6:16-19.
In ancient Israelite culture, truth and falsehood were not merely philosophical concepts but had covenantal and relational weight. A 'lie' (כָּזָב) broke community trust and violated the command against bearing false witness. Its application to idols reflects the Israelite worldview that pagan gods were not just 'other gods' but non-existent, deceptive 'nothings' (Jeremiah 10:14-15), a powerful polemic against surrounding polytheistic cultures.
שֶׁקֶר (sheqer, H8267) — a very close synonym for falsehood, often used interchangeably, but can emphasize the intent to deceive. כָּחַשׁ (kāchash, H3584) — to deny, lie, or fail; often used in contexts of denying or deceiving in a relational or covenantal context. תַּהְפֻּכוֹת (tahpukhot, H8419) — perverse or crooked things; emphasizes twisted or subverted speech rather than simple untruth.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
