1 Samuel 14:32-33

32So they quickly took sheep, cows and calves from the Philistines as food to eat. The soldiers were so hungry that they killed the animals on the ground. Then they ate the meat with the blood still in it.

33Someone told Saul, ‘Look at what the army is doing. They are eating meat that still has blood in it. That is a sin against the Lord.’ Saul said to his soldiers, ‘You have turned against the Lord! Find a large stone and roll it here to me.’
