### Core Meaning & Semantic Range
The Greek word **apokleíō**, represented by `{{G608}}`, means **to close fully** or **shut up**. It is a compound word derived from ἀπό (from) and κλείω (to close), emphasizing a complete and decisive action. This specific term appears only **1 time** in **1 unique verse** in the Bible, giving its single usage significant weight.
### Biblical Occurrences & Contextual Analysis
The sole appearance of `{{G608}}` is in a parable of Jesus found in [[Luke 13:25]]. Here, the **master of the house** rises up and has **shut** the door. This action establishes a point of finality. Those who arrive late begin to stand outside and knock, but it is too late. The master’s action of shutting the door is irreversible, leading to his declaration, "I know you not whence ye are" [[Luke 13:25]]. The use of **apokleíō** here illustrates a definitive moment of separation.
### Related Words & Concepts
Several related words help clarify the context of this final closure:
* `{{G2374}}` **thýra** (door): This word for a portal or entrance is the object that is shut. In contrast to being closed, Christ speaks of himself as the **door** [[John 10:9]] and sets before believers an open **door** that no man can shut [[Revelation 3:8]].
* `{{G2925}}` **kroúō** (knock): This word, meaning to rap, describes the action of those who are too late. The call to **knock** so a door may be opened is a recurring theme [[Matthew 7:7]], but in the context of `{{G608}}`, the knocking comes after the opportunity has passed.
* `{{G455}}` **anoígō** (open): This is the direct counterpart to shutting a door. It represents access and acceptance. In response to knocking, the promise is that the door will be **opened** [[Luke 11:9]], but this is contingent on acting before it is shut fully.
* `{{G3617}}` **oikodespótēs** (master of the house): This term refers to the head of a family who has the authority to shut the door. This figure is used in parables to represent divine authority and judgment [[Matthew 21:33]].
### Theological Significance
The theological weight of `{{G608}}` is concentrated in its single, powerful use.
* **The Point of No Return:** The act of shutting the door signifies a decisive and irreversible moment. It illustrates that there is a finite window of opportunity for entry, after which access is denied.
* **Divine Authority and Separation:** The action is performed by the **master of the house** `{{G3617}}`, establishing his authority to determine who is inside and who remains without `{{G1854}}`. The result is a final separation based on the master's judgment.
* **The Consequence of Delay:** The scene emphasizes the tragedy of those who arrive too late. Their subsequent knocking `{{G2925}}` and pleading are futile because the door has already been shut `{{G608}}`, highlighting a theme of readiness and the danger of procrastination.
### Summary
In summary, while **apokleíō** `{{G608}}` is a rare word, its context in [[Luke 13:25]] makes it profoundly significant. It conveys not just a simple closing, but a complete and final shutting that marks a point of irreversible separation. It serves as a stark reminder of divine authority, the finality of judgment, and the critical importance of responding to God's call in the time allotted.
