24 And all the people were with Saul, about twenty thousand men, and the fight was general through all the hill-country of Ephraim; but Saul made a great error that day, by putting the people under an oath, saying, Let that man be cursed who takes food before evening comes and I have given punishment to those who are against me. So the people had not a taste of food.
Matthew Henry's Commentary on 1 Samuel 14:24
Commentary on 1 Samuel 14:24-35
(Read 1 Samuel 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.
