Judges 15:3-5
3
Samson said to them, "This time I will be blameless in regard of the Philistines, when I harm them."
4
Samson went and caught three hundred foxes, and took torches, and turned tail to tail, and put a torch in the midst between every two tails.
5
When he had set the brands on fire, he let them go into the standing grain of the Philistines, and burnt up both the shocks and the standing grain, and also the olive groves.
