1 Samuel 14:32-35

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.”

34Then Saul said, “Disperse yourselves among the people and tell them: ‘Each one of you bring me his ox or his sheep, and butcher them here and eat. Don’t sin against Adonai by eating with the blood.’” So all the people each brought his ox with him that night and butchered it there.

35Then Saul built an altar to Adonai; it was the first altar that he built to Adonai.
