### Biblical Occurrences & Contextual Analysis
In scripture, `{{G3571}}` is used in several distinct contexts. It denotes the literal time of day, often a period for toil, such as when the disciples fished all **night** and caught nothing [[Luke 5:5]].

Figuratively, **night** is contrasted with day to symbolize a state of spiritual unawareness. Paul urges believers to cast off the works of darkness because "the **night** is far spent, the day is at hand" [[Romans 13:12]].

### Theological Significance
The theological weight of `{{G3571}}` is significant, symbolizing several key spiritual realities.

Believers are warned against the behaviors associated with this darkness, such as drunkenness and sleeping, which happen in the **night** [[1 Thessalonians 5:7]].
* **A Time of Enduring Faithfulness:** Despite its negative connotations, the **night** is also portrayed as a time for persistent devotion. The elect cry out to God "day and **night**" [[Luke 18:7]], and Paul speaks of serving God and preaching "night and day" ([[2 Timothy 1:3]]; [[1 Thessalonians 2:9]]).

* **A Temporary State to be Abolished:** In the eternal state, the conditions symbolized by **night** are completely eliminated. In the new creation, "there shall be no **night** there," for the glory of God provides the light ([[Revelation 21:25]]; [[Revelation 22:5]]).
