1 Samuel 14:37-41

37So Saul asked God, “Should we go after the Philistines? Will you help us defeat them?” But God made no reply that day.

38Then Saul said to the leaders, “Something’s wrong! I want all my army commanders to come here. We must find out what sin was committed today.

39I vow by the name of the Lord who rescued Israel that the sinner will surely die, even if it is my own son Jonathan!” But no one would tell him what the trouble was.

40Then Saul said, “Jonathan and I will stand over here, and all of you stand over there.” And the people responded to Saul, “Whatever you think is best.”

41Then Saul prayed, “O Lord, God of Israel, please show us who is guilty and who is innocent.” Then they cast sacred lots, and Jonathan and Saul were chosen as the guilty ones, and the people were declared innocent.
