So the Lord saved Israel that day, &c. And a wonderful salvation it was, that two men should throw such a vast army into confusion, which issued in the utter rout and destruction of them; this only could be of the Lord, to whom it is justly ascribed, and was the effect of his sovereign good will and pleasure, and of his unmerited goodness; a free favour bestowed on an undeserving prince, who had behaved ill to his prophet at Gilgal, and now to him and his high priest at Gibeah:
and the battle passed over unto Bethaven; the men of battle or war; those that made war, as the Targum, these pursued and went as far as Bethaven, or rather "passed Bethaven" (q); they not only, went as far as that, but "from" it, as Ben Gersom and Abarbinel interpret it; they passed that place, and went on from thence in pursuit of the Philistines; for their camp at Michmash was eastward from this place, and had it on the east, 1-Samuel 13:5.
(q) "transiit Bethaven", Montanus, Junius & Tremellius, Piscator; "vel, beliatores transierunt Bethaven", Pagninus, Vatablus, Drusius.
So the Lord saved Israel that day: and the battle passed over unto Beth-aven--that is, "Beth-el." It passed over the forest, now destroyed, on the central ridge of Palestine, then over to the other side from the eastern pass of Michmash (1-Samuel 14:31), to the western pass of Aijalon, through which they escaped into their own plains.
"Thus the Lord helped Israel that day, and the conflict went out beyond Bethaven." Bethaven was on the east of Michmash, and, according to 1-Samuel 14:31, the Philistines fled westwards from Michmash to Ajalon. But if we bear in mind that the camp of the Philistines was on the eastern side of Michmash before Bethaven, according to 1-Samuel 13:5, and that the Israelites forced their way into it from the south, we shall see that the battle might easily have spread out beyond Bethaven, and that eventually the main body of the enemy might have fled as far as Ajalon, and have been pursued to that point by the victorious Israelites.
The battle - That is, the warriors who were engaged in the battle, and were pursuing the Philistines. Yet it is said, the Lord saved Israel that day: he did it by them: for without him they could do nothing. Salvation is of the Lord.
