Judges 4:20-21

20He said to her, “Stand watch at the entrance to the tent. If anyone comes along and asks you, ‘Is there a man here?’ say ‘No.’”

21Then Jael wife of Heber took a tent peg in one hand and a hammer in the other. She crept up on him, drove the tent peg through his temple into the ground while he was asleep from exhaustion, and he died.
