Judges 15:3-5

3And Samson said to them, “This time I shall be blameless regarding the Philistines if I harm them!”

4Then Samson went and caught three hundred foxes; and he took torches, turned the foxes tail to tail, and put a torch between each pair of tails.

5When he had set the torches on fire, he let the foxes go into the standing grain of the Philistines, and burned up both the shocks and the standing grain, as well as the vineyards and olive groves.
