### Core Meaning & Semantic Range
The Greek word **synomoréō**, represented by `{{G4927}}`, means **to border together** or **adjoin**. Its definition is derived from Greek words for "together" and "border." This specific term is exceptionally rare, appearing only **1 time** in **1 unique verse** in the entire Bible, where it is translated as "join hard."
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G4927}}` occurs in the book of Acts. After departing from a specific location, Paul enters the house of a man named Justus, who is described as a worshipper of God. The scripture notes that Justus's house "joined hard" to the synagogue, establishing a direct physical proximity between Paul's new base of operations and the established Jewish place of worship [[Acts 18:7]].
### Related Words & Concepts
Two other words in this verse provide crucial context for the meaning of `{{G4927}}`:
* `{{G4576}}` **sébomai**: This word means **to revere, i.e. adore**, and is used to describe Justus as one who "worshipped" God [[Acts 18:7]]. Those described with this term are also referred to as "devout" or "religious" in other passages ([[Acts 13:50]], [[Acts 13:43]]).
* `{{G4864}}` **synagōgḗ**: Defined as an **assemblage of persons** or a Jewish **"synagogue"**, this is the building that Justus's house adjoined [[Acts 18:7]]. The synagogue was a central place for teaching and worship [[Matthew 4:23]], but could also represent institutional opposition, as in the "synagogue of Satan" [[Revelation 2:9]].
### Theological Significance
While `{{G4927}}` is a simple descriptive term, its single appearance carries significant symbolic weight based on its context.
* **Physical Proximity:** The word highlights the literal nearness of Paul's new ministry location (Justus's house) to the synagogue he had just departed. This emphasizes that the gospel message was being presented directly alongside traditional Judaism.
* **A Bridge Between Worlds:** Justus is described as one who "worshipped" God `{{G4576}}`, and his home, which "joined hard" `{{G4927}}` to the synagogue, becomes the new center for Paul's outreach. This physical arrangement illustrates the gospel message finding a home right at the border of the established religious community.
* **Transition of Ministry:** The use of `{{G4927}}` marks a pivotal moment of transition. Paul moves from ministering within the synagogue to a new space provided by a devout man, a space that is literally touching the former one.
### Summary
In summary, `{{G4927}}` is a highly specific word whose importance comes from its singular, context-rich application. It literally means "to join hard," and its use in [[Acts 18:7]] paints a vivid picture of a strategic and symbolic shift in Paul's ministry. The house of a devout worshipper becomes the new locus for the gospel, physically adjoining the very synagogue from which Paul had moved on.
