The answer is: Earthquake

1 Sam 14:14-15

When Jonathan launched his bold attack on the Philistine garrison, he wouldn't have anticipated the thunderous earthquake that coincided with his audacious move. This seismic event not only showcased the excitement of his plan, but it acted as a divine endorsement, amplifying the chaos and fear among his enemies. Isn’t it fascinating how nature sometimes steps in during crucial moments in biblical tales?

You can trace throughout the scriptures instances where natural events signify God’s presence or influence — think of the plagues in Egypt with hailstorms and darkness that heralded divine action, or the thunderous display at Mount Sinai that accompanied Moses receiving the law. These moments candidly exhibit a cosmic drama unfolding alongside earthly conflicts.

Moreover, there’s a growth narrative occurring here: Jonathan, intimate with the challenges of becoming a leader, learns that courage and faith are powerful forces — formidable enough to shake the ground beneath one's feet. Just as this seismic jolt turned the tide, life comes with many shaking moments that can either thwart or bolster us, depending primarily on our response to them.

Isn't it also something to reflect on that throughout history people interpreted earthquakes in varied ways? In many cultures, they’ve been seen as omens or interventions from the divine. Jonathan's story echoes the recurring theme in the Bible that underscores how faith combined with action can lead to the most dramatic of victories — or shake the very foundations of opposition.
