Judges 4:17-18, 20-21

Now Sisera fled away on foot to the tent of Jael the wife of Heber the Kenite, for there was peace between Jabin the king of Hazor and the house of Heber the Kenite. Jael went out to meet Sisera, and said to him, “Turn aside, my master, turn aside to me! Do not be afraid.” And he turned aside to her into the tent, and she covered him with a rug.

He said to her, “Stand in the doorway of the tent, and it shall be if anyone comes and inquires of you, and says, ‘Is there anyone here?’ that you shall say, ‘No.’ ” But Jael, Heber’s wife, took a tent peg and seized a hammer in her hand, and went secretly to him and drove the peg into his temple, and it went through into the ground; for he was sound asleep and exhausted. So he died.
