Judges 15:5-9

He lit the torches and set the foxes loose in the grain fields of the Philistines, burning all their grain to the ground, including the sheaves and the standing grain, as well as their vineyards and olive groves. “Who did this?” the Philistines demanded. “Samson,” someone told them, “because his father-in-law from Timnah gave Samson’s bride to his best man.” So the Philistines went and burned both the woman and her father to death. “Because you did this despicable act,” Samson vowed, “I won’t rest until I get even with you!” He was so furious that he launched a vicious attack on the Philistines and single handedly slaughtered many of them. Afterward, he went and hid in a cave in the cliff of Etam. The Philistines retaliated by setting up camp in Judah and deploying their men near the town of Lehi.
