'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.

Later on, Delilah told Samson, "You're still mocking me and telling me lies! Tell me how to tie you up!" He answered her, "If you weave the seven locks on my head into a loom and fasten it with a peg, then I will become weak and just like any other human being."

So Delilah took the seven locks on his head and wove them into the loom while he slept. She fastened his hair with a peg and then told him, "The Philistines are attacking you, Samson!" But he woke up from his nap and pulled the pin from the loom and the weaving.
