### Core Meaning & Semantic Range
The Greek word **kaítoi**, represented by `{{G2543}}`, is a conjunction meaning **although** or **nevertheless**. It appears only **1 time** in **1 unique verse** in the Bible, but its placement creates a significant theological contrast. The word is used to introduce a statement that stands in opposition to or qualifies the preceding clause, highlighting a tension between two realities.
### Biblical Occurrences & Contextual Analysis
The single biblical use of `{{G2543}}` is in [[Hebrews 4:3]], where it draws a distinction between the ongoing process of entering God's rest and the fact that this rest has been available since creation. The verse states that believers enter into rest, **although** the works were finished from the foundation of the world. This usage emphasizes that while God's provision of rest is a completed act, human entry into that rest is a continuing process contingent on belief [[Hebrews 4:3]].
### Related Words & Concepts
Several related words from its context help clarify the meaning of God's completed work and the rest He offers:
* `{{G2663}}` **katápausis** (reposing down, i.e. (by Hebraism) abode:--rest): This is the central theme of the passage. The promise is for believers to enter "his **rest**" [[Hebrews 4:1]], which is the very thing God established after His works were finished.
* `{{G1096}}` **gínomai** (to cause to be ("gen"-erate), i.e. (reflexively) to become (come into being)... be finished): This verb confirms the completion of God's work. The verse uses it to state that "the works were **finished**" from the world's foundation [[Hebrews 4:3]].
* `{{G2041}}` **érgon** (toil (as an effort or occupation); by implication, an act:--deed, doing, labour, work): This refers to God's creative acts. These **works** were completed, establishing the rest that believers are called to enter [[Hebrews 4:3]].
* `{{G1487}}` **ei** (a primary particle of conditionality; if, whether, that, etc.): This word appears in the oath quoted in the same verse, "**if** they shall enter into my rest" [[Hebrews 4:3]], establishing the conditional nature of entering the rest that stands in contrast to the certainty of its completion.
### Theological Significance
The theological weight of `{{G2543}}` is derived entirely from its single, pivotal use.
* **The Finished Work of God:** The word "although" sets up a contrast to underscore that God's provision of rest is not a future event but one that was finalized "from the foundation of the world" [[Hebrews 4:3]]. God’s part is complete.
* **Rest Through Faith:** The primary clause states that "we which have believed do enter into rest" [[Hebrews 4:3]]. The use of `{{G2543}}` serves to highlight that although the rest is a finished reality, it is accessed only through active faith `{{G4100}}`.
* **Divine Provision and Human Response:** By using `{{G2543}}`, the author creates a theological tension between God’s sovereign, completed action and the necessary human response. The rest is available, yet it must be entered into by those who believe.
### Summary
In summary, `{{G2543}}` is a rare but powerful conjunction. Its single appearance in [[Hebrews 4:3]] is structurally crucial, creating a contrast that is central to the Bible's teaching on salvation and faith. It masterfully separates the completed, sovereign work of God in providing rest from the ongoing responsibility of humanity to enter that rest through belief.
