Then he said, "Go among the troops and tell them, 'Each man must bring me his ox or his sheep, slaughter them in this place, and then eat. Do not sin against the LORD by eating meat with the blood still in it.'" So that night everyone brought his ox and slaughtered it there.

But you must not eat meat with its lifeblood still in it.

1 Samuel 14:33
Then someone reported to Saul: "Look, the troops are sinning against the LORD by eating meat with the blood still in it." "You have broken faith," said Saul. "Roll a large stone over here at once."

1 Samuel 14:35
Then Saul built an altar to the LORD; it was the first time he had built an altar to the LORD.

And Saul said, Disperse yourselves among the people, and say to them, Bring me here every man his ox, and every man his sheep, and slay them here, and eat; and sin not against the LORD in eating with the blood. And all the people brought every man his ox with him that night, and slew them there.
