1 Samuel 14:28-31

28Then one of the soldiers told him, “Your father forced the troops to take a solemn oath: ‘Cursed is anyone who eats food today.’ ” Now, the army was exhausted.

29Jonathan answered, “My father has brought trouble to the country. See how my eyes lit up when I tasted a little of this honey?

30If only the troops had eaten some of the enemies’ food, which they found today. We would have killed more Philistines.”

31That day they struck down the Philistines from Michmash to Aijalon, but the troops were thoroughly exhausted.
