Judges 20:39-41

39the Israelites counterattacked. Benjamin had begun to strike down the Israelites; they struck down about thirty men. They said, “There’s no doubt about it! They are totally defeated as in the earlier battle.”

40But when the signal, a pillar of smoke, began to rise up from the city, the Benjaminites turned around and saw the whole city going up in a cloud of smoke that rose high into the sky.

41When the Israelites turned around, the Benjaminites panicked because they could see that disaster was on their doorstep.
