### Core Meaning & Semantic Range
The Greek word **hekousíōs**, represented by `{{G1596}}`, is an adverb meaning to act voluntarily. Derived from the same root as ἑκούσιον, it is translated as **wilfully** or **willingly**. It appears **2 times** in **2 unique verses**, highlighting the significance of voluntary action in both a negative and positive light.
### Biblical Occurrences & Contextual Analysis
The two uses of `{{G1596}}` present a sharp contrast in biblical application. In [[Hebrews 10:26]], it describes the grave nature of sinning **wilfully** after one has received the **knowledge** `{{G1922}}` of the **truth** `{{G225}}`. This deliberate choice to sin results in a state where "there remaineth no more **sacrifice** `{{G2378}}` for **sins** `{{G266}}`". Conversely, in [[1 Peter 5:2]], it is used positively. Elders are instructed to **feed** `{{G4165}}` God's flock **willingly**, not by **constraint** `{{G317}}`, but with a ready mind.
### Related Words & Concepts
Several related words help clarify the meaning of `{{G1596}}` in its contexts:
* `{{G264}}` **hamartánō** (to err, especially (morally) to sin): This is the action that, when done wilfully, carries severe consequences in [[Hebrews 10:26]].
* `{{G1922}}` **epígnōsis** (full discernment, acknowledgement): This describes the state of "knowledge" one has before sinning wilfully, making the act a conscious rejection of truth [[Hebrews 10:26]].
* `{{G225}}` **alḗtheia** (truth): This is what is received and acknowledged prior to the wilful sin mentioned in [[Hebrews 10:26]].
* `{{G317}}` **anankastōs** (compulsorily): This word is used in [[1 Peter 5:2]] as the direct opposite of serving "willingly," highlighting that service should not be done under compulsion.
* `{{G4290}}` **prothýmōs** (with alacrity): Used alongside "willingly" in [[1 Peter 5:2]], this emphasizes that service should be done not just voluntarily but with a ready mind and eagerness.
### Theological Significance
The theological weight of `{{G1596}}` is centered on the concept of human will and intent.
* **The Gravity of Wilful Sin:** The use in [[Hebrews 10:26]] establishes a distinction between unintentional error and a deliberate, high-handed choice to **sin** `{{G264}}` against acknowledged **truth** `{{G225}}`. This is not a simple mistake but a conscious turning away, which is why it jeopardizes the availability of a **sacrifice** `{{G2378}}`.
* **The Heart of Ministry:** In [[1 Peter 5:2]], the command to serve **willingly** underscores that the motivation behind ministry is as important as the act itself. God desires service that flows from a voluntary and ready mind, not from mere obligation or for personal gain.
* **Volition in Faith:** Together, the two occurrences show that God assesses the direction of the will. The word differentiates between a will set against God (wilful sin) and a will submitted to God (willing service).
### Summary
In summary, `{{G1596}}` is a precise adverb that, despite its infrequent use, carries significant theological implications. It defines the crucial difference between actions done by choice versus those done by compulsion. Whether describing the deliberate act of sinning against the truth or the heartfelt service of a shepherd, **hekousíōs** reveals that the posture of the will is of paramount importance in one's relationship with God.
