John Gill Bible Commentary

But he stood in the midst of the ground,.... The field of lentiles: and defended it; the field, so that the Philistines could not ravage it, and get food and forage from it: and slew the Philistines; made a great slaughter among them, entirely routed them, so that they that escaped his sword were obliged to flee: and the Lord wrought a great victory; to whom the glory of it belonged; a similar fact is ascribed to Eleazar before mentioned in Ch1 11:13; and, indeed, it seems to be the same, and in which they were both concerned; for it is plain from the account that there were more than one engaged in this action, since it is there said, "and they set themselves in the midst of that parcel"; and though that parcel of ground is said there to be full of barley, it may easily be reconciled by observing, that one part of it might be sowed with barley, and the other part with lentiles; so the Targum in Ch1 11:13; for it was half lentiles and half barley; and Eleazar might be placed to defend the one, and Shammah the other; from whence it appears it was about March when this action was, at the latter end of which barley harvest began.
