The answer is: Sword

Luke 22:25-38

In this curious moment from Luke, Jesus is preparing His disciples for a time of trials and challenges, emphasizing that their former passive existence would soon change as they face opposition. When He instructs them to sell their cloaks to buy swords, He isn't asking them to take up arms for violence. Instead, this call for swords must be understood in the historic and symbolic context—a metaphor for preparedness.

But here’s a fun piece of trivia: the Greek word for "sword" (μάχαιρα) emphasizes it being a small sword or dagger, rather than a gigantic broadsword typically wielded by mercenaries or warriors. It signifies personal defense rather than inciting wide-scale conflict. Jesus urges His disciples not just to arm thanks to worldly threats, but also to be prepared for the persecutions that lay ahead due to spreading His transformative message.

Throughout the Bible, swords have symbolic meanings. For instance, consider Hebrews 4:12, describing the Word of God as sharper than any two-edged sword, capable of penetrating soul and spirit. It points to the spiritual weaponry believers hold—their beliefs and teachings.

So, as we delve into this call for swords from Jesus, let's see it as a reflective nudge towards spiritual readiness and embracing rather than rushing towards armed conflict. Think of it as an emblem of vigilance, particularly significant as one grapples with the life-altering and powerful words in their own journey of faith.
