כַּחַשׁ
literally a failure of flesh, i.e. emaciation; figuratively, hypocrisy
Definition
The Hebrew word כַּחַשׁ (kachash) carries a primary physical meaning of 'leanness' or 'emaciation,' describing a state of physical wasting or failure of flesh, as seen in Job 16:8 where Job describes his gaunt appearance as a witness against him. Figuratively, and more commonly in the prophets, it denotes 'deceit,' 'falsehood,' or 'hypocrisy,' referring to a moral or spiritual failure. This figurative sense is prominent in passages like Hosea 10:13 and 11:12, where it describes the deceptive and unfaithful practices of Israel. In some contexts, such as Psalm 59:12 and Nahum 3:1, the word is directly translated as 'lies,' emphasizing verbal deception and the destructive consequences that follow.
Biblical Usage
כַּחַשׁ is used six times in the Old Testament, primarily in poetic and prophetic books. Its usage splits between a literal, physical description (Job 16:8) and a metaphorical description of deceit. The metaphorical sense dominates in the Prophets, particularly in Hosea (7:3; 10:13; 11:12), where it characterizes Israel's covenant unfaithfulness and political treachery. In Psalm 59:12, it denotes the spoken falsehoods of David's enemies, and in Nahum 3:1, it labels Nineveh as a 'city of bloodshed, utterly deceitful.' The pattern shows a word that connects internal corruption (spiritual/moral) with external consequences.
Etymology
The noun כַּחַשׁ (kachash) is derived from the root verb כָּחַשׁ (kachash, H3584), which means 'to be untrue,' 'to deny,' or 'to fail.' This root connection clearly ties the physical notion of 'failing' or 'wasting away' (leanness) to the moral concept of 'being untrue' (deceit). The semantic development moves from a concrete, observable failure of the body to an abstract, internal failure of truthfulness and integrity.
Semantic Range
This word is theologically significant as it vividly links physical and spiritual reality. The imagery of 'leanness' graphically portrays the debilitating effect of sin and deception on both the individual (Job) and the covenant community (Israel). It underscores that hypocrisy and faithlessness are not merely abstract wrongs but have a corrosive, wasting effect on life and relationship with God. Understanding this Hebrew term enriches reading by revealing how biblical authors saw deceit as a force that consumes and diminishes, making passages in Hosea and the Psalms more potent.
In its ancient Near Eastern context, 'leanness' was a visible sign of poverty, famine, disease, or divine judgment. To describe deceit or hypocrisy with this term was to say it was equally visible, debilitating, and shameful. The cultural understanding of covenant loyalty (hesed) made acts of כַּחַשׁ—political betrayal and idolatry—not just personal sins but national crimes that threatened the community's very survival, which is why the prophets use it so forcefully.
שֶׁקֶר (sheqer, H8267) — a more common general term for falsehood or lie, often used for deceptive speech. כָּזָב (kazav, H3577) — denotes a lie or falsehood, often with a sense of emptiness or lack of substance. מִרְמָה (mirmah, H4820) — conveys deceit or treachery, often involving cunning or trickery.

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.
