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.
