Adam Clarke on 1 Samuel 14:24

Saul had adjured the people - He was afraid, if they waited to refresh themselves, the Philistines would escape out of their hands, and therefore he made the taking any food till sunset a capital crime. This was the very means of defeating his own intention; for as the people were exhausted for want of food, they could not continue the pursuit of their enemies: had it not been for this foolish adjuration, there had been a greater slaughter of the Philistines, 1Sam 14:30.
