### Core Meaning & Semantic Range
The Greek word **ēchéō**, represented by `{{G2278}}`, means **to make a loud noise, i.e. reverberate**. Its English translations from the base definition are **roar** and **sound**. It appears only **2 times** across **2 unique verses**, but each usage provides a distinct and powerful image.
### Biblical Occurrences & Contextual Analysis
The two appearances of `{{G2278}}` illustrate its dual application to both metaphorical and literal noise. In [[1 Corinthians 13:1]], it is used figuratively to describe a person who speaks without charity, becoming like meaningless "**sounding** brass". In contrast, [[Luke 21:25]] uses the word literally to describe an eschatological sign, where the sea and the waves will be "**roaring**" as part of a great distress of nations.
### Related Words & Concepts
Several related words help contextualize the meaning of `{{G2278}}`:
* `{{G2980}}` **laléō** (to talk, i.e. utter words): This word for speaking or talking appears in [[1 Corinthians 13:1]], establishing the context that even eloquent speech, without charity, is reduced to the empty noise of `{{G2278}}`.
* `{{G214}}` **alalázō** (to vociferate... to clang): In [[1 Corinthians 13:1]], this word is paired directly with `{{G2278}}` to complete the imagery of hollow noise, as in "**sounding** brass, or a **tinkling** cymbal".
* `{{G4535}}` **sálos** (a vibration, i.e. (specially), billow): This word for **waves** is the direct subject of the action in [[Luke 21:25]], identifying the source of the **roaring** sound.
### Theological Significance
The theological weight of `{{G2278}}` is demonstrated in its two distinct contexts.
* **Sound without Substance:** In [[1 Corinthians 13:1]], the word serves as a powerful warning. Spiritual expression, represented by speaking, becomes a hollow and useless **sound** if it is not motivated by charity. It highlights that the quality and intent behind an action are more significant than the action itself.
* **Sign of Cosmic Distress:** The word's use in [[Luke 21:25]] ties it to prophecy and the end times. The **roaring** of the sea is not merely a natural event but a divine sign of perplexity and turmoil upon the earth, signifying a world in upheaval.
### Summary
In summary, `{{G2278}}` is a potent but rare word in the biblical text. Though it appears only twice, it effectively contrasts the literal, awesome **roar** of creation in distress with the metaphorical, empty **sound** of human action devoid of divine love. It powerfully illustrates how the same concept of a loud noise can signify both prophetic power and spiritual emptiness.
