### Core Meaning & Semantic Range
The Greek word **aphypnóō**, represented by `{{G879}}`, means to **fall asleep**. It is a very specific term that appears only **1 time** in the Bible. The word is formed from a compound of ἀπό and ὕπνος, and its definition indicates a transition, "properly, to become awake, i.e. (by implication) to drop (off) in slumber."
### Biblical Occurrences & Contextual Analysis
The single biblical use of `{{G879}}` occurs in the narrative of Jesus and his disciples crossing a lake in a ship. The passage states that as they sailed, "he **fell asleep**" [[Luke 8:23]]. This simple action is placed in immediate and stark contrast to the events that follow, where a violent storm of wind comes down on the lake, filling the boat with water and placing the disciples in a state of jeopardy.
### Related Words & Concepts
Several related words from its sole context help build the scene around Jesus's sleep:
* `{{G2978}}` **laîlaps** (storm, tempest): This describes the sudden, violent squall that descended on the water, creating the dangerous situation [[Luke 8:23]]. A parallel account also describes a great **storm** arising [[Mark 4:37]].
* `{{G2597}}` **katabaínō** (to descend): This verb highlights the origin and suddenness of the storm, which "**came down**" upon the lake [[Luke 8:23]]. The term is also used theologically, noting that every good gift **cometh down** from the Father [[James 1:17]].
* `{{G2793}}` **kindyneúō** (to undergo peril): This word powerfully conveys the disciples' experience, stating they "**were in jeopardy**" [[Luke 8:23]]. Paul uses the same term to describe facing constant danger [[1 Corinthians 15:30]].
### Theological Significance
The theological weight of `{{G879}}` comes entirely from its dramatic placement within the Gospel narrative.
* **Rest Amidst Chaos:** The primary significance is the contrast between Jesus, who **fell asleep**, and the raging storm `{{G2978}}` that put his followers in peril `{{G2793}}`. His ability to rest demonstrates a profound peace that is independent of external circumstances.
* **Demonstration of Humanity:** The act of falling asleep is a clear indicator of Jesus's humanity. He was subject to the same physical needs as his disciples, requiring rest after a day of ministry.
* **Setting the Stage for Authority:** Jesus's sleep is the critical event that precedes the miracle. His state of being asleep during a crisis creates the conditions for his disciples' fear and, subsequently, for his divine authority over wind `{{G417}}` and water `{{G3041}}` to be revealed.
### Summary
In summary, while **aphypnóō** `{{G879}}` appears just once, its context gives it great significance. The act of falling asleep, described in [[Luke 8:23]], is not a minor detail but a pivotal element of the story. It illustrates the humanity of Jesus, contrasts his peace with the disciples' fear, and sets the stage for a powerful demonstration of His command over the forces of nature.
