'Tent pin' in the Bible

Then Jael Heber's wife took a tent-pin, and took a hammer in her hand, and went softly to him, and struck the pin into his temples, and it pierced through into the ground, for he was in a deep sleep, so he fainted and died.

And, behold, as Barak pursued Sisera, Jael came out to meet him, and said to him, Come, and I will show thee the man whom thou seek. And he came to her, and, behold, Sisera lay dead, and the tent-pin was in his temples.

She put her hand to the tent-pin, and her right hand to the workmen's hammer. And with the hammer she smote Sisera; she struck through his head. Yea, she pierced and struck through his temples.
