1 Samuel 14:32-33

32So 1the people loudly rushed upon the spoils, and took sheep, oxen, and calves, and slaughtered them on the ground; and the people ate them 2with the blood.

33Then observers informed Saul, saying, “Look, the people are 3sinning against the Lord by eating meat with the blood.” And he said, “You have acted treacherously; roll a large rock to me today.”
