Judges 20:37-39

Modern English Version

³⁷ So the ambushing force rushed on and attacked Gibeah. They struck down the whole city with the edge of the sword. ³⁸ The men of Israel had made an agreement with the ambushing force that when they sent up a large amount of smoke from the city, ³⁹ the children of Israel would turn around in battle.

When the Benjamites had begun to strike the children of Israel down, about thirty men, they said, “Surely they are struck down before us like at the beginning.”
