1 Samuel 14:24, 28

And the men of Israel were distressed that day; for Saul had adjured the people, saying, Cursed be the man that eateth any food until it be evening, and I be avenged on mine enemies. So none of the people tasted food.

Then answered one of the people, and said, Thy father straitly charged the people with an oath, saying, Cursed be the man that eateth food this day. And the people were faint.
