1st Samuel 14:38

35 And Saul built an altar unto the LORD: the same was the first altar that he built unto the LORD.

36 And Saul said, Let us go down after the Philistines by night, and spoil them until the morning light, and let us not leave a man of them. And they said, Do whatsoever seemeth good unto thee. Then said the priest, Let us draw near hither unto God.

37 And Saul asked counsel of God, Shall I go down after the Philistines? wilt thou deliver them into the hand of Israel? But he answered him not that day.

38 And Saul said, Draw ye near hither, all the chief of the people: and know and see wherein this sin hath been this day.

39 For, as the LORD liveth, which saveth Israel, though it be in Jonathan my son, he shall surely die. But there was not a man among all the people that answered him.

40 Then said he unto all Israel, Be ye on one side, and I and Jonathan my son will be on the other side. And the people said unto Saul, Do what seemeth good unto thee.

41 Therefore Saul said unto the LORD God of Israel, Give a perfect lot. And Saul and Jonathan were taken: but the people escaped.
