Judges 15:5-9

When he had set fire to the torches, he released the foxes into the standing grain of the Philistines, thus burning up both the shocks and the standing grain, along with the vineyards and groves. Then the Philistines said, “Who did this?” And they said, “Samson, the son-in-law of the Timnite, because he took his wife and gave her to his companion.” So the Philistines came up and burned her and her father with fire. Samson said to them, “Since you act like this, I will surely take revenge on you, but after that I will quit.” He struck them ruthlessly with a great slaughter; and he went down and lived in the cleft of the rock of Etam. Then the Philistines went up and camped in Judah, and spread out in Lehi.
