1 Samuel 14:33-34

Then 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.” And Saul said, “Disperse yourselves among the people and say to them, ‘Let every man bring his ox or his sheep and slaughter them here and eat, and do not sin against the LORD by eating with the blood.’” So every one of the people brought his ox with him that night and they slaughtered them there.
