(31) From Michmash to Aijalon.--The battle and pursuit had then extended some twenty miles of country. Again the extreme weariness of the Israelites is mentioned. Aijalon, the modern Yalo, is some eighteen or twenty miles from Michmash, where the main body of the Philistine army had been encamped.

14:24-35 Saul's severe order was very unwise; if it gained time, it lost strength for the pursuit. Such is the nature of our bodies, that daily work cannot be done without daily bread, which therefore our Father in heaven graciously gives. Saul was turning aside from God, and now he begins to build altars, being then most zealous, as many are, for the form of godliness when he was denying the power of it.And they smote the Philistines that day from Michmash to Aijalon,.... Michmash was the place where the camp of the Philistines was when Jonathan first attacked them, and from whence they fled, and they were pursued by the Israelites that day as far as Aijalon. There was a city of this name in the tribe of Dan, famous for the moon standing still in a valley adjoining to it, in the time of Joshua, Joshua 10:12 and another in the tribe of Zebulun, Judges 12:12, but they both seem to be at too great a distance to be the place here meant, which rather seems to be Aijalon in the tribe of Judah, 2 Chronicles 11:10 according to Bunting (z), it was twelve miles from Michmash:

and the people were very faint; as they might well be, with pursuing the enemy so many miles, and doing so much execution among them, without eating any food.
