Judges 20:34 Meaning and Commentary

Judges 20:34

And there came against Gibeah ten thousand chosen men out of
all Israel
Which, according to Ben Gersom, were the liers in wait; and came from the south, as the Targum says:

and the battle was sore;
not between those liers in wait, and the Benjaminites, but between those at Baaltamar, and them who set themselves in battle array against them, and they fought stoutly on both sides:

but they knew not that evil was near them;
that there was an ambush laid, by which they were in great danger; they knew nothing of the 10,000 men that were now come out against Gibeah, and were between them and that.
