1 Samuel 14:41-42

41Then Saul prayed to the Lord, Israel's God. He said, ‘Please show us who has done this sin. Let the special stones, Urim and Thummim, show who has done it.’ The stones chose Jonathan and Saul. They did not choose the soldiers of the army.

42Then Saul said, ‘Let the stones show whether it was Jonathan or me.’ The stones chose Jonathan.
