### Core Meaning & Semantic Range
The Greek word **pararrhyéō**, represented by `{{G3901}}`, means to flow by or, figuratively, to carelessly pass or miss. It is translated as **let slip**. This word appears only **1 time** in **1 unique verse** in the Bible, making its single usage particularly significant.
### Biblical Occurrences & Contextual Analysis
The sole appearance of `{{G3901}}` is in [[Hebrews 2:1]], which serves as a powerful exhortation: "Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should **let them slip**." In this context, the word paints a vivid picture of spiritual truths drifting away due to neglect or inattention. It warns believers against passively and carelessly losing hold of the message they have received.
### Related Words & Concepts
Several surrounding words in [[Hebrews 2:1]] give crucial context to the warning against letting things slip:
* `{{G4337}}` **proséchō** (give heed): This verb means to pay attention to, be cautious about, or apply oneself to something. It is the necessary action to prevent the passive drifting described by `{{G3901}}`. It is used to warn against false prophets [[Matthew 7:15]] and to call for attention to sound doctrine [[1 Timothy 4:1]].
* `{{G1163}}` **deî** (ought): This word signifies that something is necessary or binding. Its use in [[Hebrews 2:1]] frames the act of giving heed not as a suggestion but as a moral and spiritual obligation, as seen in contexts where things "must" be fulfilled [[Luke 24:44]] or where prayer "ought" to be constant [[Luke 18:1]].
* `{{G3379}}` **mḗpote** (lest at any time): This term expresses a warning about a potential negative outcome. It highlights the constant possibility of letting truth slip away if one is not vigilant, similar to the warning to "take heed... lest at any time your hearts be overcharged" [[Luke 21:34]].
### Theological Significance
The theological weight of `{{G3901}}` is concentrated in its single, impactful use. It underscores several critical themes:
* **The Danger of Spiritual Drifting:** The word's root meaning, "to flow by," illustrates that falling away can be a passive process of careless drifting rather than an act of overt rebellion. It is a warning against spiritual apathy.
* **The Necessity of Diligence:** The command is not merely to hear truth, but to give "more earnest" `{{G4056}}` "heed" `{{G4337}}` to it. This directly counters the carelessness implied by `{{G3901}}`, highlighting that maintaining one's hold on the gospel requires active, sustained attention.
* **The Value of What is Heard:** The object that must not be "let slip" are "the things which we have heard" `{{G191}}`. This places immense importance on the received message of the gospel and warns against treating it lightly. The call is to be a doer of the word, not just a hearer [[Matthew 7:24]].
### Summary
In summary, `{{G3901}}` provides a unique and potent image within the New Testament. Though used only once, **pararrhyéō** serves as a vital warning against the subtle danger of spiritual neglect. It illustrates the peril of allowing foundational truths to "flow by" and underscores the corresponding, non-negotiable call for believers to actively and earnestly hold fast to what they have heard.
