KJV: Then Jael Heber's wife took a nail of the tent, and took an hammer in her hand, and went softly unto him, and smote the nail into his temples, and fastened it into the ground: for he was fast asleep and weary. So he died.
NASB: 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.
