The Greek word brýchō, represented by G1031, is a primary verb that means to gnash or grate the teeth. According to usage statistics, it appears only 1 time in 1 unique verse in the Bible. The definition specifies this action as a response to pain or rage.
The single biblical occurrence of G1031 is in Acts 7:54. This verse captures the intense and hostile reaction to Stephen's sermon. After the audience heard G191 "these things" G5023, the scripture states they "were cut G1282 to the heart G2588... and G2532 they gnashed G1031 on him with their teeth G3599." The action serves as a physical manifestation of their inner fury and conviction.
Several words found within its immediate context help clarify the meaning of G1031:
- G1282 diapríō (cut (to the heart)): Defined as to "saw asunder" or figuratively "to exasperate," this describes the internal state of severe emotional agitation that precedes the gnashing of teeth Acts 7:54.
- G2588 kardía (heart): The location of the emotional turmoil. It represents the "thoughts or feelings (mind)" which were "cut" by Stephen's message Acts 7:54.
- G3599 odoús (tooth): The physical instrument used to perform the action of gnashing. The verse explicitly connects the rage to the physical act involving their teeth Acts 7:54.
- G191 akoúō (to hear): This is the catalyst for the entire event. The intense reaction of being cut to the heart and gnashing teeth was triggered when they heard the message Acts 7:54.
The thematic weight of G1031 is concentrated in its single appearance, highlighting a powerful reaction against divine truth.
- A Sign of Rage: The act of gnashing teeth is a raw, physical expression of uncontrollable rage and hostility directed at a messenger of God.
- Rejection of Conviction: The response in Acts 7:54 is critical. Upon hearing the truth, the people are "cut to the heart," a moment of deep conviction. Instead of leading to repentance, this conviction curdles into rage, expressed through G1031.
- Precursor to Violence: This display of rage is not the end of the action but the boiling point immediately preceding the violent act of stoning Stephen.
In summary, G1031 is a potent verb that, while rare, provides a stark image of defiant rage. It is not simply about being angry; it specifically illustrates a hostile response to a spiritual truth that convicts the heart. Its singular use in Acts 7:54 powerfully connects an internal, emotional state of being "cut" with an external, violent expression of gnashing teeth.
