Judges 20:42

unto the way of the wilderness in the direction of the barren hilly region, E. of Gibeah, which descends from the Central Highlands to the Jordan valley.

out of the cities i.e. the Benjamite cities on the line of the flight. But all the male Benjamites had been out with the army, and most of them killed: so read out of the city, i.e. Gibeah; the reference will then be to the men who formed the ambush. For in the midst thereof(lit. of him) read in the midst, as Joshua 8:22. The Benjamites suddenly found themselves caught between Israelites in front and rear. The men of Ai were intercepted in the same way.

The verse comes from the B narrative: cf. Judges 20:21; Judges 20:25destroyed them. With the correction of the text the marg. becomes unnecessary.
