1 Samuel 14:40-41

40Saul said to all the Israelites, ‘You stand on this side. My son Jonathan and I will stand on the other side.’ The people answered, ‘Do what you think is right.’

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.
