'Peg' in the Bible

While he was sleeping from exhaustion, Heber’s wife Jael took a tent peg, grabbed a hammer, and went silently to Sisera. She hammered the peg into his temple and drove it into the ground, and he died.

When Barak arrived in pursuit of Sisera, Jael went out to greet him and said to him, “Come and I will show you the man you are looking for.” So he went in with her, and there was Sisera lying dead with a tent peg through his temple!

She reached for a tent peg,her right hand, for a workman’s mallet.Then she hammered Sisera—she crushed his head;she shattered and pierced his temple.
