What does Judges 20:45 mean?
Israel's eleven other tribes have turned the tables on the twelfth tribe, Benjamin. The fighters of Benjamin's army believed they had all but won their third battle. Instead, the Israelites drew them out with a false retreat and cut them off from their base at Gibeah, burning it to the ground (Judges 20:29–32; 40–42). This results in the Benjaminites being almost surrounded. Already, most of Benjamin's soldiers have been killed (Judges 20:43–44).Those warriors who remain are attempting to run to the wilderness to escape. Their immediate goal is a place called the "rock of Rimmon." Scholars suggest this was a set of limestone cliffs not far from Gibeah and Geba. These cliffs are full of countless holes and caves, perfect for hiding from enemies.
Very few of those fleeing made it to safety. The Israelite soldiers overran and killed almost every Benjaminite soldier. When the battle is over, only about one in twenty of Benjamin's initial forces will be alive (Judges 20:15, 26).
