1 Samuel 14:31-33

They struck among the Philistines that day from Michmash to Aijalon. And the people were very weary. The people rushed greedily upon the spoil, and took sheep and oxen and calves, and slew them on the ground; and the people ate them with the blood. Then they told Saul, saying, “Behold, the people are sinning against the LORD by eating with the blood.” And he said, “You have acted treacherously; roll a great stone to me today.”
