Judges 4:18-21 CJB

18 Ya'el went out to meet Sisra and said to him, "Come in, my lord; stay here with me; and don't be afraid." So he went into her tent, and she covered him with a blanket.
19 He said to her, "Please give me a little water to drink - I'm thirsty." She opened a goatskin of milk, gave him some to drink, and covered him up again.
20 He said to her, "Stand at the entrance to the tent; and if anyone asks you if somebody is here, say, 'No.'"
21 But when he was deeply asleep, Ya'el the wife of Hever took a tent peg and a hammer in her hand, crept in to him quietly and drove the tent peg into his temple, right through to the ground; so that he died without waking up.
