זְנוּת
adultery, i.e. (figuratively) infidelity, idolatry
Definition
The Hebrew noun זְנוּת (zᵉnûwth) primarily denotes 'whoredom' or 'adultery' in a literal, physical sense. However, its most significant usage in the Old Testament is figurative, representing spiritual infidelity and idolatry, where Israel's worship of other gods is portrayed as marital unfaithfulness to Yahweh (e.g., Jeremiah 3:9, Ezekiel 23:27). In some contexts, it describes the literal sexual immorality that accompanies idolatrous practices (e.g., Hosea 4:11). The word also appears in a unique, non-sexual sense in Numbers 14:33, where God declares the Israelites will bear the consequences of their 'whoredoms'—their faithless complaints and rebellion in the wilderness.
Biblical Usage
זְנוּת is used exclusively in prophetic and historical books to condemn Israel's covenant unfaithfulness. It appears most frequently in the prophets Jeremiah, Ezekiel, and Hosea, where it is a central metaphor for idolatry. For example, Jeremiah 3:2 and 13:27 accuse Judah of being polluted by her 'whoredoms' with idols on the hills. Ezekiel 43:7, 9 uses it to describe the idolatrous practices that defiled the temple. The pattern is clear: the term is a powerful theological indictment of breaking the exclusive covenant relationship with God.
Etymology
Derived from the root verb זָנָה (zānâ, H2181), meaning 'to commit fornication, to be a harlot, or to be unfaithful.' This root conveys the core ideas of illicit sexual activity and, by extension, illicit religious activity. זְנוּת is the noun form that encapsulates the state or practice of such infidelity.
Semantic Range
This word is theologically central to understanding the covenant relationship between God and Israel, which is often depicted as a marriage. זְנוּth powerfully encapsulates the sin of idolatry not as a mere ritual error but as a profound betrayal of intimate trust and exclusive commitment. Grasping this Hebrew concept enriches reading of the prophets, revealing why idolatry is treated with such severity—it is spiritual adultery. It also deepens the understanding of God's grace, as He is portrayed as a faithful husband seeking to restore an unfaithful wife (e.g., the book of Hosea).
In ancient Near Eastern culture, marriage was a covenant of exclusive loyalty. Adultery was a capital offense, violating the family's fundamental social and economic unit. When prophets used זְנוּת to describe idolatry, their audience immediately understood the gravity of the accusation: it was a capital offense against the covenant with God. Furthermore, pagan fertility religions often involved ritual prostitution, creating a direct link between literal 'whoredom' and idolatrous worship in the cultural mind, a connection explicitly made in passages like Hosea 4:11-14.
נִאוּף (niʾûph, H5003) — focuses more specifically on the act of adultery itself. תּוֹעֵבָה (tôʿēbâ, H8441) — a broader term for 'abomination,' often including idolatrous and sexually immoral practices. זִמָּה (zimmâ, H2154) — denotes lewdness, wicked plans, or vile acts, often in a context of sexual and religious depravity.

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.
