Samson's wife betrayed him on the last day of the wedding feast by revealing the secret of the riddle to the Philistine wedding guests. He left his wife in a rage. After he had cooled down, Judges 15:
1 Later on, at the time of the wheat harvest, Samson took a young goat and went to visit his wife. “I want to go to my wife in her room,” he said. But her father would not let him enter.
2“I was sure that you thoroughly hated her,” said her father, “so I gave her to one of the men who accompanied you. Is not her younger sister more beautiful than she? Please take her instead.”
His wife did him wrong. Now his father-in-law seemed to have done him wrong. He decided to take it out on some unrelated Philistines.
3 Samson said to them, “This time I will be blameless in doing harm to the Philistines.”
4 Then 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.
This seems to be an act of terror on some random Philistines.
What was Samson's logic in verse 3?
