### Core Meaning & Semantic Range
The Greek word **eusebéō**, represented by `{{G2151}}`, is used to define the act of being pious. It appears **2 times** across **2 unique verses** in the Bible. The term's definition is twofold: it can refer to the act of worship directed toward God, or the act of showing respect and support toward one's parents.
### Biblical Occurrences & Contextual Analysis
The two uses of `{{G2151}}` in scripture highlight its dual meaning. In Acts, the word describes the act of religious worship. Paul, observing an altar to an "UNKNOWN GOD" in Athens, tells the people, "Whom therefore ye ignorantly **worship**, him declare I unto you" [[Acts 17:23]]. Conversely, in his letter to Timothy, Paul uses the word to describe a familial duty, instructing that children or nephews should "learn first to **shew piety** at home, and to requite their parents" [[1 Timothy 5:4]]. This act of honoring parents is presented as something "acceptable before God."
### Related Words & Concepts
Several related words help clarify the context of piety and worship:
* `{{G2316}}` **theós** (a deity, especially the supreme Divinity): This word is central to the concept of worship. Paul uses `{{G2151}}` to correct the Athenians' worship, directing it toward the true **God** [[Acts 17:23]]. Similarly, showing piety to parents is deemed acceptable before **God** [[1 Timothy 5:4]].
* `{{G4574}}` **sébasma** (something adored, i.e. an object of worship): This term refers to the objects of the Athenians' reverence. Paul beholds their "devotions" just before discussing whom they ignorantly **worship** `{{G2151}}`, linking the general act of adoration to the specific act of worship [[Acts 17:23]].
### Theological Significance
The theological significance of `{{G2151}}` is demonstrated in its application to both divine and human relationships.
* **Actionable Piety:** The word emphasizes that piety is not merely a belief but an active practice. This is seen in the instruction to "shew piety at home" by supporting parents [[1 Timothy 5:4]] and in the act of worship, even when misdirected [[Acts 17:23]].
* **Worship Redefined:** In Athens, the use of `{{G2151}}` serves as a bridge from pagan practice to true worship. Paul affirms the Athenians' instinct to worship but seeks to direct it from an unknown object to the living God he declares [[Acts 17:23]].
* **The Link Between Earthly Duty and Divine Pleasure:** By stating that showing piety to parents is "acceptable before God," scripture connects familial responsibility directly to divine approval. Honoring parents becomes an expression of piety toward God [[1 Timothy 5:4]].
### Summary
In summary, `{{G2151}}` encapsulates the concept of active piety. Though used sparingly, its applications are significant, spanning from the proper worship of God to the dutiful respect shown to family. It illustrates that in biblical thought, reverence is a tangible action, and fulfilling earthly duties like caring for one's parents is an act of piety that is pleasing to God.
