The answer is: Drove a tent peg into his head

Judg 4:21

Ah, the bold and fascinating character of Jael! Her story unfolds amidst the backdrop of Israelite oppression, where remarkable women like her took decisive actions when needed. Picture the scene: Sisera, the commander of the Canaanite army, flees after a disastrous battle against the Israelites, led by the fearless Deborah. He seeks refuge in the tent of Jael, who represents a most unlikely hero.

Culturally, tents were symbols of hospitality. Yet, Jael's hospitality turned into one of the most dramatic turning points in biblical history. While the men who were supposed to protect the people faltered, Jael strategically used what was at hand—quite literally—a tent peg and a hammer. The act itself might seem shocking, but within the broader narrative, it symbolizes the triumph of the underdog, showcasing that victory isn't solely the province of the trained warrior.

This act echoes themes found elsewhere in Scripture, where ordinary people catalyze extraordinary events. Think of David confronting Goliath—a young shepherd triumphing over a seasoned giant—showing that faith coupled with courage can redefine outcomes.

Jael’s action also touches on the incremental gains women made in cultural narratives across antiquity, reflecting their mistrust with power dynamics prevalent in that era. It’s fascinating to consider how her legacy transcends her immediate context, inspiring those who feel marginalized or voiceless to pave impactful paths in unpredictable ways. Her mustard seed of faith led her to stand boldly against a tyrannical force, embedded in history as a figure of audacious strength.
