1 Samuel 14:28-31

28Then answered one of the people and said, Thy father strictly adjured the people, saying, Cursed be the man that eateth food this day; and the people are faint.

29And Jonathan said, My father has troubled the land: see, I pray you, that mine eyes are bright, because I tasted a little of this honey.

30How much more, if the people had eaten freely to-day of the spoil of their enemies which they found? for would there not now have been a much greater slaughter among the Philistines?

31And they smote the Philistines that day from Michmash to Ajalon; and the people were very faint.
