Judges 4:17-18, 20-21

Sisera, meanwhile, fled on foot to the tent of Jael, the wife of Heber the Kenite, because there was an alliance between Jabin king of Hazor and the family of Heber the Kenite. Jael went out to meet Sisera and said to him, “Come, my lord, come right in. Don’t be afraid.” So he entered her tent, and she covered him with a blanket.

“Stand in the doorway of the tent,” he told her. “If someone comes by and asks you, ‘Is anyone in there?’ say ‘No.’ ” But Jael, Heber’s wife, picked up a tent peg and a hammer and went quietly to him while he lay fast asleep, exhausted. She drove the peg through his temple into the ground, and he died.
