moicheuó: To commit adultery

Original Word: μοιχεύω
Part of Speech: Verb
Transliteration: moicheuó
Pronunciation: moy-KHYOO-oh
Phonetic Spelling: (moy-khyoo'-o)
Definition: To commit adultery
Meaning: I commit adultery (of a man with a married woman, but also of a married man).

Word Origin: Derived from the Greek word μοιχός (moichos), meaning "adulterer."

Corresponding Greek / Hebrew Entries: - H5003 (נָאַף, na'aph): To commit adultery

- H5004 (נֹאף, no'ef): Adulterer

Usage: The verb "moicheuó" refers to the act of committing adultery, which is engaging in sexual relations with someone who is not one's spouse. In the New Testament, it is used both in a literal sense and metaphorically to describe unfaithfulness to God.

Cultural and Historical Background: In the ancient Jewish context, adultery was considered a serious violation of the Mosaic Law, which prescribed severe penalties for those found guilty (Leviticus 20:10). Adultery was not only a personal sin but also a social offense that disrupted family and community integrity. In the Greco-Roman world, while views on sexual morality varied, adultery was generally frowned upon and could have legal repercussions.
