1 Samuel 23:3,4

David's men said, Behold, we are afraid here in Judah “They had more than difficulty enough to defend themselves against Saul where they were; and could it be less than madness to provoke more and greater enemies? Doubtless Saul would send forces to beat off the Philistines, and then they should be pent in between two hostile armies. And yet, notwithstanding all this, David undertook and achieved the adventure; which it was impossible he should, against such fears, and such reasonings of his forces, from any motive other than the assurance of divine protection and aid. Which fully confirms the Scripture account of this matter, that he did not undertake it until he had, for the fuller satisfaction of his associates, again consulted, and was again assured of success by the divine oracle.”
