1st Samuel 14:38

35 And Saul put up an altar to the Lord: this was the first altar which he put up to the Lord.

36 And Saul said, Let us go down after the Philistines by night, attacking them till the morning, till there is not a man of them living. And they said, Do whatever seems right to you. Then the priest said, Let us come near to God.

37 And Saul, desiring directions from God, said, Am I to go down after the Philistines? will you give them up into the hands of Israel? But he gave him no answer that day.

38 And Saul said, Come near, all you chiefs of the people, and let us get word from God and see in whom is this sin today.

39 For, by the living Lord, the saviour of Israel, even if the sinner is Jonathan, my son, death will certainly be his fate. But not a man among all the people gave him any answer.

40 Then he said to all Israel, You be on one side, and I with Jonathan my son will be on the other side. And the people said to Saul, Do whatever seems good to you.

41 Then Saul said to the Lord, the God of Israel, Why have you not given me an answer today? If the sin is in me or in Jonathan my son, O Lord God of Israel, give Urim, and if it is in your people Israel, give Thummim. And by the decision of the Lord, Saul and Jonathan were marked out, and the people went free.
