1 Samuel 14:27-28

14:27 But Jonathan had not heard about the oath his father had made the army take. He extended the end of his staff that was in his hand and dipped it in the honeycomb. When he ate it, his eyes gleamed. 14:28 Then someone from the army informed him, “Your father put the army under a strict oath saying, ‘Cursed be the man who eats food today!’ That is why the army is tired.”
