### Core Meaning & Semantic Range
The Greek word **kleís**, represented by `{{G2807}}`, is defined as a **key**, used both literally and figuratively for shutting a lock. It is derived from the verb `{{G2808}}` kleíō, meaning "to shut." The word appears **6 times** across **6 unique verses** in the Bible, consistently symbolizing authority and control.
### Biblical Occurrences & Contextual Analysis
In scripture, `{{G2807}}` is used to denote significant spiritual authority. The resurrected Christ declares, "I am he that liveth... and have the **keys** of hell and of death" [[Revelation 1:18]], signifying his ultimate power over these realms. This authority is also described as the "**key** of David," which allows him to open what no one can shut and shut what no one can open [[Revelation 3:7]]. This same concept of authority is delegated when Jesus gives Peter the "**keys** of the kingdom of heaven" [[Matthew 16:19]]. The word is also used to represent access to understanding, as when Jesus chastises the lawyers for having "taken away the **key** of knowledge" [[Luke 11:52]].
### Related Words & Concepts
Several related words help clarify the function and meaning of a **key**:
* `{{G2808}}` **kleíō** (to close (literally or figuratively):--shut (up)): As the root verb, it describes one of the primary actions of a key. This is seen in the declaration that Christ has the key and "shutteth, and no man openeth" [[Revelation 3:7]].
* `{{G455}}` **anoígō** (to open up (literally or figuratively, in various applications):--open): This is the direct counterpart to shutting. The one who possesses the key of David is he that "openeth, and no man shutteth" [[Revelation 3:7]].
* `{{G1210}}` **déō** (a primary verb; to bind (in various applications, literally or figuratively):--bind, be in bonds, knit, tie, wind): The authority of the keys is directly linked to the power to bind. Jesus promises that "whatsoever thou shalt **bind** on earth shall be bound in heaven" [[Matthew 16:19]].
* `{{G3089}}` **lýō** (a primary verb; to "loosen"): The complementary power to binding is loosing. The one given the keys is also told, "whatsoever thou shalt **loose** on earth shall be loosed in heaven" [[Matthew 16:19]].
### Theological Significance
The theological weight of `{{G2807}}` is centered on the concept of divine authority and access.
* **Sovereign Authority:** The **key** is a symbol of absolute power belonging to Christ. He holds the **keys** of death [[Revelation 1:18]], the **key** of David [[Revelation 3:7]], and grants the **key** to the bottomless pit ([[Revelation 9:1]], [[Revelation 20:1]]), demonstrating his complete control over life, death, and spiritual domains.
* **Delegated Authority:** The "keys of the kingdom of heaven" given to Peter represent authority delegated to believers on earth to act in accordance with heaven's will, specifically in matters of binding and loosing [[Matthew 16:19]].
* **Access to Truth:** The "key of knowledge" signifies the means of entering into true understanding. Taking this **key** away is a grave offense, as it hinders others from entering into a right relationship with God [[Luke 11:52]].
### Summary
In summary, `{{G2807}}` is a potent biblical symbol representing far more than a physical instrument. It signifies sovereign authority, delegated power, and exclusive access. Whether used to describe Christ's dominion over death, the church's stewardship of the gospel, or control over spiritual realms, the **key** consistently points to the power to open and to shut, to bind and to loose, granting or restricting entry as its holder decrees.
