The answer is: A sharp sword

Rev 1 vs 16

In the vivid imagery of Revelation, it’s striking to consider that a sharp sword comes from the mouth of Jesus. This is not merely a weapon; it's a symbolic representation of power, judgment, and truth. In ancient times, swords were often associated with authority and military might, suggesting that Jesus carries a profound truth that has the ability to pierce through deception and injustice.

This motif is echoed elsewhere in Scripture, albeit in different forms. For instance, Hebrews 4:12 refers to the word of God as "living and active, sharper than any two-edged sword," emphasizing its capability to discern thoughts and intentions. While traditional interpretations may focus on the notion of divine judgment, there’s something deeply compelling about how truth can cut through the noise of worldly affairs, bringing clarity and insight.

Interestingly, in both Hebrew and Greek, the term for sword can have a dual meaning, reflecting both physical and spiritual conflict. The symbolism in Revelation invites us to explore themes of spiritual warfare where what we say, or more significantly, what Christ speaks, has the power to bring about change in our lives and in the world.

In this context, the sword’s sharpness serves not just to expose wrongdoing but also delivers liberation from the chains of ignorance. It urges us to consider how we wield our words—are they instruments of healing or harm? The divine message encourages us to see our communication as a means to advocate for justice and compassion in our communities.
