1 Samuel 14:30-33
English Standard Version
31They struck down the Philistines that day from Michmash to Aijalon. And the people were very faint.
32The people pounced on the spoil and took sheep and oxen and calves and slaughtered them on the ground. And the people ate them with the blood.
33Then they told Saul, "Behold, the people are sinning against the Lord by eating with the blood." And he said, "You have dealt treacherously; roll a great stone to me here."
