### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{G4083}}` is used to illustrate concepts of scale and limitation. In both Matthew and Luke, it is used in a rhetorical question asking who by worrying can add a single **cubit** to their stature, highlighting human inability to alter divine providence ([[Matthew 6:27]], [[Luke 12:25]]). The word is also used to describe a literal distance, where the disciples in a boat were about two hundred **cubits** from land [[John 21:8]]. Lastly, it is used in a descriptive measurement of the New Jerusalem, where an angel measured its wall to be one hundred and forty-four **cubits** [[Revelation 21:17]].
### Related Words & Concepts
Several related words provide a broader context for measurement and quantity:
* `{{G1250}}` **diakósioi** (two hundred): This word for a specific number is used directly with **cubit** to define a distance in John's gospel [[John 21:8]]. It is also used to count people, days, and money ([[Acts 27:37]], [[Revelation 11:3]], [[Mark 6:37]]).
* `{{G3354}}` **metréō** (to measure): This verb describes the action of measuring. It is used in the account where the wall of the new city is **measured** in cubits [[Revelation 21:17]]. It is also used figuratively, as in the principle that one will be **measured** by the same standard they use for others [[Mark 4:24]].
* `{{G3358}}` **métron** (a measure): This noun refers to a standard or a limited portion. It is used in Revelation to clarify that the angelic measurement in **cubits** was "according to the **measure** of a man" [[Revelation 21:17]]. It is also used metaphorically to speak of the "**measure** of faith" [[Romans 12:3]].
### Theological Significance
The theological weight of `{{G4083}}` is seen in its contrasting applications.
* **Human Limitation:** The **cubit** is used to represent a small, seemingly achievable addition to human life or stature, yet it is presented as something beyond human control. This emphasizes the futility of anxiety and the sovereignty of God over human life ([[Matthew 6:27]], [[Luke 12:25]]).
* **Divine Measurement:** In Revelation, the **cubit** becomes a unit used in a divine and angelic act of measuring the holy city. This grounds the magnificent vision of the New Jerusalem in a familiar, human-scale unit, signifying divine order and perfection that is still comprehensible [[Revelation 21:17]].
* **Physical Reality:** Its use in John's gospel to measure the distance from a boat to the shore serves to ground a post-resurrection appearance of Jesus in a real-world, tangible setting [[John 21:8]].
### Summary
In summary, `{{G4083}}` functions as more than a simple unit of length. As a **cubit**, it is a tool for understanding scale in different biblical contexts. It is used to teach a lesson on the limits of human worry, to ground a historical narrative in physical space, and to describe the perfect and divinely ordered dimensions of God's coming kingdom. The word effectively bridges the gap between the human and the divine, from the smallness of a single **cubit** to the grand measurement of a heavenly city.
