Judges 4:21-22

But Jael, Heber’s wife, took a tent peg and seized a hammer in her hand, and went secretly to him and drove the peg into his temple, and it went through into the ground; for he was sound asleep and exhausted. So he died. And behold, as Barak pursued Sisera, Jael came out to meet him and said to him, “Come, and I will show you the man whom you are seeking.” And he entered with her, and behold Sisera was lying dead with the tent peg in his temple.
