Strong's Lexicon
zelos: Zeal, jealousy, ardor, fervor

Original Word: ζῆλος
Part of Speech: Noun, Masculine; Noun, Neuter
Transliteration: zelos
Pronunciation: ZAY-los
Phonetic Spelling: (dzay'-los)
Definition: Zeal, jealousy, ardor, fervor
Meaning: (a) eagerness, zeal, enthusiasm, (b) jealousy, rivalry.

Word Origin: Derived from the verb ζέω (zeo), meaning "to boil" or "to be hot."

Corresponding Greek / Hebrew Entries: - קִנְאָה (qin'ah) - Strong's Hebrew 7068, often translated as "jealousy" or "zeal."

- קָנָא (qana) - Strong's Hebrew 7065, a verb meaning "to be jealous" or "to be zealous."

Usage: In the New Testament, "zelos" can have both positive and negative connotations. Positively, it refers to an intense enthusiasm or fervor for something good, such as devotion to God or a righteous cause. Negatively, it can denote jealousy or envy, where one's fervor is misdirected or self-centered.

Cultural and Historical Background: In the Greco-Roman world, "zelos" was often associated with the competitive spirit and rivalry, especially in athletic and political contexts. In Jewish culture, zeal was a highly regarded trait, especially in religious contexts, where it was seen as a passionate commitment to God's law and covenant. The Zealots, a Jewish political movement, exemplified this fervor in their resistance against Roman occupation.

HELPS Word-studies

2205 zḗlos (an omamopoeic term that mimics the sound of water bubbling over from heat and perhaps derived from 2204 /zéō, "to boil") – properly, burning emotion (inner feeling boiling over, "boiling from heat," J. Thayer); (figuratively) something very fervent ("red-hot") as with Spirit-fueled zeal to serve the Lord. This root (zē-) is used both negatively ("jealousy") and positively ("zeal") depending on the context.

[The root (zē-, "zeal") literally means "hot enough to boil." It is metaphorically used of "burning anger, love, zeal" (A-S) – i.e. to burn (in spirit). It can refer to "boiling anger, love, zeal, for what is good or bad" (J. Thayer).]
