1 Samuel 14:33-34

33Then observers informed Saul, saying, “Look, the people are 1sinning against the Lord by eating meat with the blood.” And he said, “You have acted treacherously; roll a large rock to me today.”

34Then Saul said, “Disperse yourselves among the people and say to them, ‘Each one of you bring me his ox or his sheep, and slaughter it here and eat; and do not sin against the Lord by eating it with the blood.’” So all the people brought them that night, each one his ox 2with him, and they slaughtered them there.
