1 Samuel 14:35

31 That day, after the Israelites had struck down the Philistines from Michmash to Aijalon, the people were very faint.

32 So they rushed greedily to the plunder, taking sheep, cattle, and calves. They slaughtered them on the ground and ate meat with the blood still in it.

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.”

34 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.

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

36 And Saul said, “Let us go down after the Philistines by night and plunder them until dawn, leaving no man alive!” “Do what seems good to you,” the troops replied. But the priest said, “We must consult God here.”

37 So Saul inquired of God, “Shall I go down after the Philistines? Will You give them into the hand of Israel?” But God did not answer him that day.

38 Therefore Saul said, “Come here, all you leaders of the troops, and let us investigate how this sin has occurred today.

39 As surely as the LORD who saves Israel lives, even if it is my son Jonathan, he must die!” But not one of the troops said a word.
