Judges 15:4-5

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

5When he had set the torches ablaze, he let the foxes go into the standing grain of the Philistines, and he burned up the heap of sheaves and the standing grain, along with the vineyards and olive groves.
