Judges 15:3-8

3Samson said to them, “This time I will be blameless in doing harm to the Philistines.”

4Then Samson went out and caught three hundred foxes. And he took torches, turned the foxes tail-to-tail, and fastened a torch between each pair of tails. 5Then he lit the torches and released the foxes into the standing grain of the Philistines, burning up the piles of grain and the standing grain, as well as the vineyards and olive groves.

6“Who did this?” the Philistines demanded.

“It was Samson, the son-in-law of the Timnite,” they were told. “For his wife was given to his companion.”

So the Philistines went up and burned her and her father to death.

7And Samson told them, “Because you have done this, I will not rest until I have taken vengeance upon you.” 8And he struck them ruthlessly1 with a great slaughter, and then went down and stayed in the cave at the rock of Etam.
