[155] When it was related to the Israelites what the inhabitants of Gibeah had resolved upon, they took their oath that no one of them would give his daughter in marriage to a Benjamite, but make war with greater fury against them than we have learned our forefathers made war against the Canaanites; and sent out presently an army of four hundred thousand against them, while the Benjamites' army-was twenty-five thousand and six hundred; five hundred of whom were excellent at slinging stones with their left hands, insomuch that when the battle was joined at Gibeah the Benjamites beat the Israelites, and of them there fell two thousand men; and probably more had been destroyed had not the night came on and prevented it, and broken off the fight; so the Benjamites returned to the city with joy, and the Israelites returned to their camp in a great fright at what had happened. On the next day, when they fought again, the Benjamites beat them; and eighteen thousand of the Israelites were slain, and the rest deserted their camp out of fear of a greater slaughter. So they came to Bethel, ¹ a city that was near their camp, and fasted on the next day; and besought God, by Phineas the high priest, that his wrath against them might cease, and that he would be satisfied with these two defeats, and give them the victory and power over their enemies. Accordingly God promised them so to do, by the prophesying of Phineas.
