1 Samuel 14:29-33

Then Jonathan said, “My father has troubled the land. See now that my eyes have brightened because I tasted a little of this honey.

How much more, if only the people had freely eaten today of the spoils of their enemies which they found! For now the defeat among the Philistines has not been great.”

They attacked the Philistines that day from Michmash to Aijalon. But the people were very tired.

So the people loudly rushed upon the spoils, and took sheep, oxen, and calves, and slaughtered them on the ground; and the people ate them with the blood.

Then observers informed Saul, saying, “Look, the people are sinning against the Lord by eating meat with the blood.” And he said, “You have acted treacherously; roll a large rock to me today.”
