### Core Meaning & Semantic Range
The Hebrew word **ʻăyâm**, represented by `{{H5868}}`, is a term of doubtful origin believed to mean **strength** or **mighty**. It is exceptionally rare, appearing only **1 time** in **1 unique verse** in the Bible, making its sole occurrence contextually significant.
### Biblical Occurrences & Contextual Analysis
The single use of `{{H5868}}` is found in Isaiah's prophecy concerning the Lord's power. In this passage, the word describes the quality of the wind God will use to perform a miraculous act of judgment and deliverance. The verse states that the Lord will act "with his **mighty** wind" to shake his hand over the river and smite it [[Isaiah 11:15]]. This context directly links `{{H5868}}` to an instrument of divine power.
### Related Words & Concepts
Several related words from its only context help clarify its meaning:
* `{{H5130}}` **nûwph** (wave): This primitive root means to quiver, shake, or wave. In the primary verse, God will **shake** his hand with the mighty wind [[Isaiah 11:15]]. The term is also used for a priest performing a **wave** offering before the Lord [[Numbers 6:20]] or the action of a saw being shaken [[Isaiah 10:15]].
* `{{H7307}}` **rûwach** (wind, spirit): This word, which can mean wind, breath, or spirit, is the object described as **mighty** `{{H5868}}`. While it is a **wind** in [[Isaiah 11:15]], it frequently refers to the **Spirit** of God, as when the prophet declares, "The **Spirit** of the Lord GOD is upon me" [[Isaiah 61:1]].
### Theological Significance
The theological weight of `{{H5868}}` is derived entirely from its singular, powerful application.
* **Instrument of Divine Power:** The word is used exclusively to describe an instrument of God's power—a **mighty** wind—demonstrating how God utilizes creation to execute His will [[Isaiah 11:15]].
* **Sovereignty over Creation:** By qualifying the wind as **mighty**, the text emphasizes God's absolute control over natural forces, directing them to strike the Egyptian sea and remake the landscape for His purposes [[Isaiah 11:15]].
* **Force for Salvation:** The purpose of this **mighty** action is ultimately redemptive. God smites the river to "make men go over dryshod" [[Isaiah 11:15]], creating a path for his people.
### Summary
In summary, though appearing only once, **ʻăyâm** `{{H5868}}` carries significant weight. It is not a general term for strength but is uniquely applied to the wind of God in an act of both judgment and salvation. Its sole appearance in [[Isaiah 11:15]] serves as a potent descriptor of divine might, illustrating how God wields the forces of nature to accomplish His sovereign plan.
