1 Samuel 14:31-35

31They attacked the Philistines that day from 1Michmash to 2Aijalon. But the people were very tired. 32So 3the people loudly rushed upon the spoils, and took sheep, oxen, and calves, and slaughtered them on the ground; and the people ate them 4with the blood. 33Then observers informed Saul, saying, “Look, the people are 5sinning 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 6with him, and they slaughtered them there. 35And 7Saul built an altar to the Lord; it was the first altar that he built to the Lord.
