Judges 4:21

And Jael, Heber's wife, mindful of the fact that the man lying in her tent was a tyrant, a ruthless enemy of a nation with which her family was joined in the bonds of the closest relationship, took a nail of the tent, one of the tent-pins, and took an hammer in her hand, and went softly unto him, and smote the nail into his temples, and fastened it into the ground; for he was fast asleep and weary, from his long flight. So he died.
