Yael Kills Sisera With a Tent Peg
Yael welcomes the fleeing general Sisera into her tent, and once he falls asleep she kills him with a tent peg rather than a man’s sword.
This has relevance to the story in Tanach of the heroine Yael. Yael welcomed the fleeing enemy general Sisera into her tent with feigned hospitality. After drinking a refreshing beverage, Sisera lay down and soon sank into the sleep of the weary. While he lay asleep, Yael crept stealthily up to him, holding a tent peg and a mallet. She drove it through his temples with such force that it entered into the ground below.
The Mefaresh on Nazir explains why Yael killed Sisera with a tent peg rather than a sword. She didn’t want to wield a weapon that is generally used by men and thereby violate the aforementioned prohibition.
