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.
The men of Israel were very upset that day because Saul, their leader, had sworn that no one could eat until he could take revenge on his enemies. Therefore, nobody ate anything all day long.
