Judges 20:37-48 - How The Israelites Won
37 The men in ambush had rushed quickly against Gibeah; they advanced and put the whole city to the sword. 38 The men of Israel had a prearranged signal with the men in ambush: when they sent up a great cloud of smoke from the city, 39 the men of Israel would return to the battle. When Benjamin had begun to strike them down, killing about 30 men of Israel, they said, “They’re defeated before us, just as they were in the first battle.”
46 All the Benjaminites who died that day were 25,000 armed men; all were warriors. 47 But 600 men escaped into the wilderness to the rock of Rimmon and stayed there four months. 48 The men of Israel turned back against the other Benjaminites and killed them with their swords—the entire city, the animals, and everything that remained. They also burned down all the cities that remained.
