1 Samuel 14:32-33

32Then the people rushed greedily upon the plunder, took sheep, oxen and calves, butchered them on the ground, and the people ate them with the blood.

33Then they reported to Saul saying, “Behold, the people are sinning against Adonai by eating with the blood.” “You have acted faithlessly,” he said. “Roll a great stone towards me at once.”
