1 Samuel 14:28-31
28 Then one of the soldiers told him, “Your father bound the army under a strict oath, saying, ‘Cursed be any man who eats food today!’ That is why the men are faint.”
29 Jonathan said, “My father has made trouble for the country. See how my eyes brightened when I tasted a little of this honey.
30 How much better it would have been if the men had eaten today some of the plunder they took from their enemies. Would not the slaughter of the Philistines have been even greater?”
31 That day, after the Israelites had struck down the Philistines from Micmash to Aijalon, they were exhausted.
