### Core Meaning & Semantic Range
The Greek word **epidýō**, represented by `{{G1931}}`, is defined as "to set fully (as the sun):--go down." Derived from ἐπί and δύνω, its meaning is tied to the complete setting of the sun. It appears only 2 times in a single biblical verse, giving it a very specific and focused application.
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G1931}}` is found in [[Ephesians 4:26]], which commands, "Be ye angry, and sin not: let not the sun **go down** upon your wrath". Here, the physical act of the sun setting is used as a metaphorical deadline. The instruction uses this daily, natural event to place a time limit on holding onto anger, urging believers to resolve their conflicts before the end of the day.
### Related Words & Concepts
Several related words in [[Ephesians 4:26]] provide the context for the command involving `{{G1931}}`:
* `{{G2246}}` **hḗlios** (the sun; by implication, light): This is the object that performs the action of "going down." In this context, the setting of the **sun** marks the end of the day and the deadline for reconciliation.
* `{{G3710}}` **orgízō** (to provoke or enrage, i.e. (passively) become exasperated): The verse begins with an acknowledgement of anger ("Be ye **angry**"), which is the emotion that must be addressed before the action of `{{G1931}}` occurs.
* `{{G264}}` **hamartánō** (to err, especially (morally) to sin): The command links unresolved anger with the potential for sin. The time limit imposed by the sun going down is intended to prevent anger from leading to **sin**.
* `{{G3950}}` **parorgismós** (rage:--wrath): This is the specific state upon which the sun must not **go down**. It describes an intense form of anger that is particularly dangerous if left to fester.
### Theological Significance
The theological significance of `{{G1931}}` is derived entirely from its singular, powerful use in scripture.
* **A Call for Timely Reconciliation:** The use of **epidýō** establishes a concrete, daily rhythm for forgiveness and resolving conflict. It frames reconciliation not as an eventual goal but as an urgent, daily practice.
* **Preventing Lingering Sin:** The command directly links the physical timeline of a day with the spiritual danger of allowing anger to persist. By instructing believers not to let the sun **go down** on their wrath `{{G3950}}`, it provides a practical guard against the sin `{{G264}}` that unresolved anger can produce.
* **Maintaining Community Health:** Within the broader context of Ephesians, which emphasizes unity in the body of Christ, this command is crucial for maintaining relational harmony. It provides a clear, actionable step to prevent bitterness from taking root and dividing believers.
### Summary
In summary, `{{G1931}}` is a precise term meaning "to go down" that is used exclusively for the sun. Its only biblical appearance in [[Ephesians 4:26]] elevates it from a simple description of a natural event to a profound spiritual principle. The word serves as a powerful metaphor for the urgency of dealing with anger, establishing a daily deadline to ensure that conflict is resolved and does not lead to sin, thereby preserving peace and unity.
