### Core Meaning & Semantic Range
The Greek adverb **megálōs**, represented by `{{G3171}}`, is an intensive form meaning **greatly**. Derived from μέγας, it serves to express a high degree or large measure of an action. It is a rare word, appearing only **1 time** in a single verse in the entire Bible.
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G3171}}` is found in the writings of Paul, where he expresses his profound emotional state. In his letter to the Philippians, he writes, "I rejoiced in the Lord **greatly**, that now at the last your care of me hath flourished again" [[Philippians 4:10]]. Here, **megálōs** modifies the verb "rejoiced," emphasizing that Paul's joy was not minor or casual but immense and deeply felt. The word powerfully conveys the magnitude of his gladness upon receiving the support and care of the Philippian believers.
### Related Words & Concepts
The context of `{{G3171}}` is enriched by related words that also appear in its only verse:
* `{{G5463}}` **chaírō** (rejoice): This verb means to be cheerful, glad, or to rejoice. It is the very action that `{{G3171}}` intensifies in [[Philippians 4:10]]. The call to **rejoice** is a recurring theme for Paul, as seen in his command to "Rejoice in the Lord alway" [[Philippians 4:4]].
* `{{G5426}}` **phronéō** (to be careful, to mind): This word means to exercise the mind or to have a certain sentiment or concern. In [[Philippians 4:10]], Paul's great joy is a direct result of the Philippians' **care** (phronéō) for him. This same word is used to instruct believers on their mindset, such as to "Set your affection on things above" [[Colossians 3:2]].
### Theological Significance
The theological weight of `{{G3171}}`, though based on a single occurrence, is significant in its context. It highlights several key principles of Christian life and fellowship.
* **The Depth of Christian Joy:** The use of **megálōs** demonstrates that joy in the Lord is not meant to be a shallow emotion. It can be experienced profoundly and **greatly**, especially in response to God's work through His people [[Philippians 4:10]].
* **Fellowship as a Source of Joy:** Paul’s great joy is explicitly linked to the tangible **care** (phronéō) of the Philippian church. This shows that mutual support and mindful concern within the body of Christ are direct catalysts for profound spiritual rejoicing.
* **A Mindset that Leads to Rejoicing:** The connection between **phronéō** (care, mindset) and **chaírō** (rejoice) is central. Being "likeminded" and having the "mind of Christ" ([[Philippians 2:2]], 2:5) fosters an environment where the fruit is great joy.
### Summary
In summary, while `{{G3171}}` is one of the rarest words in the New Testament, its single use offers a powerful insight. It serves to magnify the emotion of joy, tying it directly to the practical, mindful care demonstrated between believers. The word **megálōs** illustrates that the Christian experience of joy is designed to be deep and substantial, fueled by a community that actively cares for one another in the Lord.
