So the children of Benjamin saw that they were smitten,.... Their forces broken and worsted, many being killed:

for the men of Israel gave place to the Benjaminites; at first, and made as if they were afraid of them, and so fled before them, which was only to decoy them to a greater distance from the city Gibeah:

because they trusted unto the liers in wait, which they had set beside Gibeah; that these would not only enter the city, and burn it, but meet the Benjaminites fleeing back to it, when they should turn upon them and smite them, and so cut off all that remained of them.

The Benjaminites, for instance, saw (this is the proper rendering of ויּראוּ with vav consec., which merely indicates the order of thought, not that of time) that they were beaten, and the man of Israel vacated the field before Benjamin (מקום נתן, to give place by falling back and flying), because they relied upon the ambush which they had placed against Gibeah. The Benjaminites did not perceive this till the ambush fell upon their rear. But the ambush itself, as is added in Judges 20:37 by way of further explanation, hastened and fell (fell as quickly as possible) into Gibeah, and went thither and smote the whole town with the edge of the sword. To this there is added the further explanation in Judges 20:38 : "And the arrangement of the Israelites with the ambush was this: multiply, to cause smoke-rising to ascend (i.e., cause a great cloud of smoke to ascend) out of the city." The only objection that can be raised to this view of הרב, as the imperative Hiphil of רבה, is the suffix ם-attached to להעלותם, since this is unsuitable to a direct address. This suffix can only be explained by supposing that there is an admixture of two constructions, the direct appeal, and the indirect explanation, that they were to cause to ascend. If this be not admitted, however, we can only follow Studer, and erase the suffix as an error of the pen occasioned by the following word משׂאת; for the other course suggested by Bertheau, namely that הרב should be struck out as a gloss, is precluded by the circumstance that there is no possible way of explaining the interpolation of so apparently unsuitable a word into the text. It certainly stood in the text used by the lxx, though they have most foolishly confounded הרב with חרב, and rendered it μάχαιρα.

So the children of Benjamin saw that they were smitten: for the men of Israel {r} gave place to the Benjamites, because they trusted unto the liers in wait which they had set beside Gibeah.

(r) Retired to draw them after.

17:7-13 Micah thought it was a sign of God's favour to him and his images, that a Levite should come to his door. Thus those who please themselves with their own delusions, if Providence unexpectedly bring any thing to their hands that further them in their evil way, are apt from thence to think that God is pleased with them.
