I Samuel 14:32-34

And the people rushed on the spoil, and took sheep, oxen, and calves, and slaughtered them on the ground; and the people ate them with the blood. Then they told Saul, saying, “Look, the people are sinning against the LORD by eating with the blood!” So he said, “You have dealt treacherously; roll a large stone to me this day.” Then Saul said, “Disperse yourselves among the people, and say to them, ‘Bring me here every man’s ox and every man’s sheep, slaughter them here, and eat; and do not sin against the LORD by eating with the blood.’ ” So every one of the people brought his ox with him that night, and slaughtered it there.
