Root / Etymology

Root: כ-ז-ב. The primary sense of the root is 'to be false' or 'to deal falsely.' The verb כָּזַב derives from this root and carries the active sense of uttering falsehoods, deceiving, or failing to be true or reliable. The noun כָּזָב ('falsehood, lie') comes from the same root.

Historical & Contextual Notes

כָּזַב occurs with the sense of personal or interpersonal deception, as in Proverbs 30:6, and also as a statement about unreliable things or promises, as in Habakkuk 2:3. In some poetic texts, it can express the disappointment of something that proves untrustworthy. The word is distinct from related terms such as שָׁקַר (shaqar), which also means 'to lie' but often carries a nuance of emptiness or vanity, or אַוֶּן (aven), which can denote iniquity or worthlessness. English versions sometimes translate כָּזַב ambiguously (e.g. 'be in vain'), but the foundational sense is falsehood or unreliability, both in human conduct and in the failure of objects or hopes to fulfill what is expected. The term is present across genres—from Torah law (e.g. prohibitions against bearing false witness) to wisdom literature and prophetic oracles—sometimes denoting overt falsehood, other times the disappointing failure of anticipated results. The meaning remains relatively stable throughout the biblical period, though in post-biblical Hebrew its use narrows mainly to personal lying or deceit. Later translation traditions (e.g., LXX, Vulgate) sometimes render it with words for 'lie' or 'vain,' occasionally contributing to a theological or moral nuance in translation.

Original Strong's Gloss (1890)

a primitive root; to lie (i.e. deceive), literally or figuratively; fail, (be found a, make a) liar, lie, lying, be in vain.
