Judges 4:20-21

20He 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.’”

21But Jael, Heber’s wife, 1took a tent peg and 2seized 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.
