Judges 20:42

40But when the cloud began to arise up out of the city in a pillar of smoke, the Benjamites looked behind them; and behold, the whole city went up in smoke to the sky.

41The men of Israel turned, and the men of Benjamin were dismayed; for they saw that disaster had come on them.

42Therefore they turned their backs before the men of Israel to the way of the wilderness, but the battle followed hard after them; and those who came out of the cities destroyed them in the middle of it.

43They surrounded the Benjamites, chased them, and trod them down at their resting place, as far as near Gibeah toward the sunrise.

44Eighteen thousand men of Benjamin fell; all these were men of valor.
