### Core Meaning & Semantic Range
The Greek word **heterozygéō**, represented by `{{G2086}}`, means **to yoke up differently** or **to associate discordantly**. It appears only **1 time** in **1 unique verse** in the Bible. This word is a compound of ἕτερος (another of a different kind) and ζυγός (a yoke), creating a powerful figurative image of a mismatched pair being forced to work together.
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G2086}}` is in [[2 Corinthians 6:14]], where a clear command is given: "Be ye not **unequally yoked together** with unbelievers." The verse immediately provides the rationale for this instruction by posing two rhetorical questions that highlight absolute incompatibility. It asks what **fellowship** `{{G3352}}` righteousness `{{G1343}}` can have with unrighteousness `{{G458}}`, and what **communion** `{{G2842}}` light `{{G5457}}` can have with darkness `{{G4655}}`. The context establishes an impassable divide between two opposing spiritual realities.
### Related Words & Concepts
Several related words from its single context clarify the meaning of being **unequally yoked together**:
* `{{G571}}` **ápistos** (disbelieving... unbeliever): This word identifies the specific group with whom discordant association is forbidden [[2 Corinthians 6:14]]. The term is used elsewhere to describe those who are "faithless" [[Matthew 17:17]].
* `{{G3352}}` **metochḗ** (participation, i.e. intercourse): Translated as **fellowship**, it questions what kind of participation is possible between the opposing forces of righteousness and unrighteousness [[2 Corinthians 6:14]].
* `{{G2842}}` **koinōnía** (partnership... communion... fellowship): Used as **communion**, this word further explores the prohibited association, questioning the partnership between light and darkness [[2 Corinthians 6:14]]. In other contexts, it describes the positive **fellowship** believers can have, such as being called into the **fellowship** of His Son [[1 Corinthians 1:9]].
* `{{G458}}` **anomía** (illegality... unrighteousness): This term represents the direct opposite of righteousness. The verse uses this contrast to illustrate why a shared "yoke" is impossible [[2 Corinthians 6:14]].
### Theological Significance
The theological weight of `{{G2086}}` is centered on the principle of spiritual separation and purity.
* **A Call to Distinction:** The command not to be **unequally yoked together** is a foundational call for believers to live lives that are distinct from those who do not share their faith. The association is with "unbelievers" `{{G571}}` [[2 Corinthians 6:14]].
* **Incompatibility of Opposites:** The word's meaning is explained through stark, mutually exclusive pairings: righteousness `{{G1343}}` and unrighteousness `{{G458}}`, and light `{{G5457}}` and darkness `{{G4655}}`. This framing shows that the command is based on a fundamental conflict of spiritual natures, not mere social preference.
* **The Nature of Fellowship:** By forbidding discordant partnerships, the verse implicitly defines proper spiritual relationships. True **fellowship** `{{G3352}}` and **communion** `{{G2842}}` are only possible between those who share the same spiritual foundation in light and righteousness [[2 Corinthians 6:14]].
### Summary
In summary, while `{{G2086}}` appears only once, its vivid imagery provides a lasting and crucial theological principle. It transcends the literal picture of mismatched animals to deliver a profound command about spiritual alliances. The term **unequally yoked together** serves as a permanent warning against forming partnerships that compromise one's fundamental identity and walk as a believer, emphasizing the absolute distinction between the realms of righteousness and unrighteousness.
