Wife of Heber the Kenite. After the battle of Kishon, the Canaanite general Sisera fled and came to her tent. She covered him, gave him milk, and when he slept she drove a tent peg through his temple with a hammer. Deborah's song calls her: "Most blessed of women be Jael." She ended the war.
On their voice
~1200 BCE. Not an Israelite — a Kenite woman, living outside the battle's allegiances. She made a choice in a moment and she made it completely. The text gives her no guilt and Deborah blesses her. She is not a villain.
Talk to Jael.
Ask anything. In their own voice, from their own era, grounded in their own canon.
