'Tent pin' in the Bible

But Jael, Heber’s wife, took a tent peg and a hammer in her hand, and came up quietly to him and drove the peg through 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 [her tent] with her, and behold Sisera lay dead with the tent peg in his temple.

“She reached out her [left] hand for the tent peg,And her right hand for the workmen’s hammer.Then she struck Sisera, she smashed his head;And she shattered and pierced his temple.
