Judges 4:17-18, 20-21

But Sisera himself ran away to the tent where Jael lived. She was the wife of Heber, one of the Kenite family groups. Heber’s family was at peace with Jabin king of Hazor. Jael went out to meet Sisera and said to him, “Come into my tent, master! Come in. Don’t be afraid.” So Sisera went into Jael’s tent, and she covered him with a rug.

He said to her, “Go stand at the entrance to the tent. If anyone comes and asks you, ‘Is anyone here?’ say, ‘No.’ ” But Jael, the wife of Heber, took a tent peg and a hammer and quietly went to Sisera. Since he was very tired, he was in a deep sleep. She hammered the tent peg through the side of Sisera’s head and into the ground. And so Sisera died.
