What does Judges 20:34 mean?
Israel's strategic battle plan has worked. The main force of Israel's army is pretending to flee to the north in defeat, luring Benjamin's forces away from the city of Gibeah (Judges 20:29–33). A second part of Israel's army emerged from hiding between the Benjaminites and the city, effectively trapping them in between. This cuts off their ability to retreat to the city.Finally, a third group of Israelite fighters engage from their positions nearer the city. These fighters have been specially chosen for their mission. Depending on how the Hebrew word 'eleph is translated, this group is either ten thousand men, or ten divisions of men. The bulk of Benjamin's army has left the city, but some have remained behind. They will be even more outnumbered than usual (Judges 20:15–17) yet can still use the city's natural defenses against their Israelite attackers.
This verse emphasizes that the battle between these elite Israelite soldiers and the remnant of the army of Benjamin is fierce. However, Israel, is on the verge of victory. At this point, Benjamin's army doesn't realize how close they are to defeat. From their perspective, their main contingent is chasing down a retreating Israelite army. Because of Israel's clever planning, their city is already as good as lost (Judges 20:35).
