'Peg' in the Bible

But Jael, the wife of Heber the Kenite, took in her hand a tent peg and a hammer, and she went softly to him and drove the peg into his temple, and it went through into the ground; he [was] fast asleep since he was exhausted, and he died.

And behold, Barak [was] pursuing Sisera, and Jael went out to meet him, and she said to him, "Come, and I will show you the man whom you [are] seeking." And he came with her and saw that Sisera was lying dead with the peg in his temple.

She reached out her hand to the peg, and her right hand for the workman's hammer; and she struck Sisera, crushed his head, and she shattered and pierced his temple.
