1 Samuel 14:37-41

37Saul asked [counsel] of God, “Shall I go down after the Philistines? Will You hand them over to Israel?” But He did not answer him that day.

38Then Saul said, “Come here, all you who are leaders of the people, and let us find out how this sin [causing God’s silence] happened today.

39For as the Lord lives, who saves Israel, for even if the guilt is in my son Jonathan, he shall most certainly die.” But not one of all the people answered him.

40Then he said to all the Israelites, “You shall be on one side; I and my son Jonathan will be on the other side.” The people said to Saul, “Do what seems good to you.”

41Therefore, Saul said to the Lord, the God of Israel, “Give a perfect lot [identifying the transgressor].” Then Saul and Jonathan were selected [by lot], but the other men went free.
