### Core Meaning & Semantic Range
The Greek word **próteros**, represented by `{{G4387}}`, is a comparative term meaning **prior** or **previous**. Its specific scriptural definition is **former**. Despite its foundational meaning related to time and sequence, it is a rare word in the Bible, appearing only **1 time** in **1 unique verse**.
### Biblical Occurrences & Contextual Analysis
The single use of `{{G4387}}` is found in [[Ephesians 4:22]], where it is central to the concept of spiritual transformation. The verse commands believers to "put off concerning the **former** conversation the old man." Here, **próteros** is used to identify a past way of life or behavior that must be discarded. This **former** life is explicitly linked to the "old man," which is described as being "corrupt according to the deceitful lusts."
### Related Words & Concepts
Several related words in its sole context illuminate the meaning of the "former" life:
* `{{G659}}` **apotíthēmi**: This word, meaning "to put away," is the direct action believers are told to take toward their **former** behavior [[Ephesians 4:22]].
* `{{G391}}` **anastrophḗ**: Defined as "behavior," this is the specific thing being described as **former**. It refers not to a single action but to a complete manner of living [[Ephesians 4:22]].
* `{{G3820}}` **palaiós**: Meaning "antique, i.e. not recent, worn out," this term describes the "man" associated with the **former** life, reinforcing the idea of leaving behind something that is old and obsolete [[Ephesians 4:22]].
### Theological Significance
The theological weight of `{{G4387}}` is concentrated in its single appearance, where it establishes a crucial doctrine:
* **Spiritual Transformation:** The word creates a clear dividing line between a believer's past and their new identity. The call to abandon the **former** conversation is a call to a radical and definitive change [[Ephesians 4:22]].
* **The "Old Man":** `{{G4387}}` is essential for defining the "old man." It is his behavior that is labeled as **former**, a lifestyle characterized by corruption and "deceitful lusts" (`{{G539}}`, `{{G1939}}`).
* **Sanctification:** By identifying a **prior** way of life to be cast off, the term underscores the ongoing process of sanctification, where a believer must consciously reject sinful patterns of the past.
### Summary
In summary, while `{{G4387}}` is used only once, its role is pivotal. It is not merely a word for "previous" but a theological marker that signifies a complete break with a past self. In [[Ephesians 4:22]], it provides the basis for understanding the Christian's separation from the "old man" and the corrupt behavior that defined that **former** existence, highlighting the theme of total life transformation.
