Judges 15:4-5

4Then he went out and caught 300 foxes. He tied their tails together in pairs, and he fastened a torch to each pair of tails.

5Then he lit the torches and let the foxes run through the grain fields of the Philistines. He burned all their grain to the ground, including the sheaves and the uncut grain. He also destroyed their vineyards and olive groves.
