Judges 4:20-21

20Then he said to her, “Stand at the entrance of the tent, and if anyone comes and asks you saying, ‘Is there a man here?’ then you will say, ‘There’s no one.’”

21Then Yael, Heber’s wife, took a tent pin and got a hammer in her hand, approached him stealthily and drove the pin into his temple until it pierced through into the ground—for he was exhausted and in a deep sleep. So he died.
