### Core Meaning & Semantic Range
The Greek word **synkalýptō**, represented by `{{G4780}}`, means **to conceal altogether** or **cover**. It is formed from the words σύν and καλύπτω. This term is exceptionally rare, appearing only **1 time** in **1 unique verse** within the Bible, highlighting a very specific concept of complete concealment.
### Biblical Occurrences & Contextual Analysis
The single use of `{{G4780}}` is found in [[Luke 12:2]], where it establishes a fundamental principle of divine accountability: "For there is nothing **covered**, that shall not be revealed; neither hid, that shall not be known." In this context, **synkalýptō** describes an attempt to hide or conceal something so thoroughly that it cannot be found. However, the verse immediately declares this action futile, as all that is **covered** will ultimately be disclosed and made known.
### Related Words & Concepts
Several related words from its biblical context help clarify the theme of concealment and revelation:
* `{{G601}}` **apokalýptō** (to take off the cover, i.e. disclose:--reveal): This word is the direct antonym used in the same verse, emphasizing that what is concealed will be revealed by God [[Luke 12:2]]. It is the action that undoes the covering.
* `{{G2927}}` **kryptós** (concealed, i.e. private:--hid(-den), inward(-ly), secret): Used in parallel with `{{G4780}}`, this term refers to things that are hidden or secret. The Bible affirms that God will judge the **secrets** of men [[Romans 2:16]] and bring to light the **hidden things** of darkness [[1 Corinthians 4:5]].
* `{{G1097}}` **ginṓskō** (to "know"): This is the ultimate outcome that opposes concealment. What is **covered** is destined to be **known** [[Luke 12:2]], a concept central to eternal life, which is to **know** God [[John 17:3]].
### Theological Significance
The theological weight of `{{G4780}}` is established by its singular, powerful context.
* **The Inevitability of Disclosure:** The primary theme is that no act of concealment is permanent before God. Everything that is **covered** will face divine revelation, underscoring the principles of final judgment and ultimate truth [[Luke 12:2]].
* **The Futility of Hiding Sin:** By stating that nothing **covered** will remain so, the verse serves as a warning against hypocrisy and hidden sin. God's knowledge penetrates all attempts to hide, as He judges the **secrets** of the heart [[Romans 2:16]].
* **God's Sovereignty over Truth:** The use of `{{G4780}}` in opposition to "revealed" `{{G601}}` and "known" `{{G1097}}` shows that God is the final arbiter of what is known. He is the one who reveals truth that was previously hidden from human understanding [[Matthew 16:17]].
### Summary
In summary, while **synkalýptō** `{{G4780}}` appears only once, its meaning is profound. It is defined entirely by its failure; its purpose is to **cover**, but its biblical context guarantees that this covering is temporary. The word serves as a crucial anchor for the theological principle that nothing can be permanently hidden from God and that all things will one day be brought into the light for judgment and revelation.
