Judges 20:31-32

31The soldiers of Benjamin came out of Gibeah to attack them. But the Israelites moved away from the city so that Benjamin's soldiers chased after them. The men of Benjamin began to kill the Israelites, as they had done before. They killed about 30 Israelites in the fields and on the roads that went to Bethel and Gibeah.

32The soldiers of Benjamin were saying, ‘We are winning against them, as we have done before!’ But the Israelites were saying, ‘We will continue to run away so that their soldiers chase us. We will lead them away from the city onto the roads.’
