1 Samuel 14:33-34

14:33 Now it was reported to Saul, “Look, the army is sinning against the Lord by eating even the blood.” He said, “All of you have broken the covenant! Roll a large stone over here to me.” 14:34 Then Saul said, “Scatter out among the army and say to them, ‘Each of you bring to me your ox and sheep and slaughter them in this spot and eat. But don’t sin against the Lord by eating the blood.” So that night each one brought his ox and slaughtered it there.
