Ambrose of Milan, on Judg 15:4

“And he went and caught three hundred foxes, and coupled them tail to tail, and fastened torches between the tails.”

“Wherefore he took three hundred foxes, and in the heat of summer, when the corn was now ripe in the fields, he tied them together two and two by the tails, and fastened a burning firebrand between them, binding it with a firm knot, and by way of avenging his wrong turned them loose among the sheaves which the Philistines had cut. But the foxes, terrified by the fire, scattered flames whichever way they turned, and burnt the harvest.”
