1 Samuel 14:23

Likewise all the men of Israel which had hid themselves in mount Ephraim, when they heard that the Philistines fled, even they also followed hard after them in the battle.

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 evening, that I may be avenged on mine enemies. So none of the people tasted any food.
