1 Samuel 14:28-29, 31-32

But one of the people told him, “Your father strictly put the people under an oath, saying, ‘Cursed be the man who eats food today.’ ” And the people were exhausted [and hungry]. Then Jonathan said, “My father has troubled the land [with his foolish curse]. See how my energy is restored because I tasted a little of this honey.

They struck the Philistines that day from Michmash to Aijalon. And the people were very tired. [When night came and the oath ended] the people rushed greedily upon the spoil. They took sheep, oxen, and calves, and slaughtered them on the ground; and they ate them [raw] with the blood [still in them].
