The answer is: Drove a tent peg into his head

Judg 4:21

In the dramatic saga found in Judges, Jael stands out as an unexpected heroine. While Israel faced oppression from Jabin, the king of Canaan, and his commander Sisera, Jael’s audacity would turn the tide. After Sisera fled the battlefield, seeking refuge, it was Jael who welcomed him into her tent. This does not just make her a pivotal figure; it also amplifies the themes of betrayal and empowerment threaded throughout scripture.

Picture Sisera, worn and weary, feeling secure in the presence of a woman. Little did he know, Jael had her own agenda! In a moment where trust turned fatal, she drove a tent peg through his temple while he lay asleep, securing victory for Israel. This act was shrouded in cultural significance too—sudden violence from an unlikely victor not only highlights her bravery but challenges traditional gender expectations of the time.

Interestingly, feminine figures in the Bible frequently embody strength in non-traditional forms, like Deborah, who precedes Jael as a judge and prophetess. The stunning finishes—in both cases foreshadow the delicate interplay of strength and vulnerability throughout the text. The name "Jael" even resonates with attributes of a goat, symbolizing strength in an unconventional form, which might arouse curiosity and admiration for how women in the scriptures wield influence in the face of overwhelming odds.

Contrastingly, Jael's story beckons reflection on the often untold narratives of women who defy stereotypes, shifting the script dramatically and ahead of their turbulent times.
