1 Samuel 14:28-30

28Then 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.”

29Then Jonathan said, “My father has caused trouble for the land. See how my eyes gleamed when I tasted just a little of this honey.

30Certainly if the army had eaten some of the enemies’ provisions that they came across today, would not the slaughter of the Philistines have been even greater?”
