1 Samuel 14:31-32
31-32They killed Philistines that day all the way from Micmash to Aijalon, but the soldiers ended up totally exhausted. Then they started plundering. They grabbed anything in sight—sheep, cattle, calves—and butchered it where they found it. Then they glutted themselves—meat, blood, the works.
33-34Saul was told, "Do something! The soldiers are sinning against God. They're eating meat with the blood still in it!"
Saul said, "You're biting the hand that feeds you! Roll a big rock over here—now!" He continued, "Disperse among the troops and tell them, 'Bring your oxen and sheep to me and butcher them properly here. Then you can feast to your heart's content. Please don't sin against God by eating meat with the blood still in it.'"
And so they did. That night each soldier, one after another, led his animal there to be butchered.
