Judges 15:4-5

4So he went out and he caught 300 foxes. He tied the foxes in pairs by their tails. He tied some dry grass to each pair of tails.

5Then he lit the grass with fire. He made the foxes run through the fields where the wheat was growing. The fire destroyed all the Philistines' crops, whether they had already cut it down or not. The fire also destroyed their vines and their olive trees.
