1 Samuel 14:27-30
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.”
14:29 Then Jonathan said, “My father has caused trouble for the land. See how my eyes gleamed when I tasted just a little of this honey.
14:30 Certainly 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?”
