1 Samuel 14:36; 1 Samuel 14:37

36 Saul said, “Let us go down and pursue the Philistines by night and plunder them till dawn, and let us not leave one of them alive.” “Do whatever seems best to you,” they replied. But the priest said, “Let us inquire of God here.”

37 So Saul asked God, “Shall I go down and pursue the Philistines? Will you give them into Israel’s hand?” But God did not answer him that day.
