Judges 4:17-21

But 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. And Jael came out to meet Sisera and said to him, “Turn aside, my lord; turn aside to me; do not be afraid.” So he turned aside to her into the tent, and she covered him with a rug. And he said to her, “Please give me a little water to drink, for I am thirsty.” So she opened a skin of milk and gave him a drink and covered him. And he said to her, “Stand at the opening of the tent, and if any man comes and asks you, ‘Is anyone here?’ say, ‘No.’” But Jael the wife of Heber took a tent peg, and took a hammer in her hand. Then she went softly to him and drove the peg into his temple until it went down into the ground while he was lying fast asleep from weariness. So he died.
