‘And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into mine hand; for he is shut in, by entering into a town that hath gates and bars.
David asks the Lord a hypothetical question: what if…? ‘Will Saul come down and pursue me here? If I stay in Keilah, will the men of the city betray me? I have just delivered them out of the hands of the Philistines, and they surely owe me an immense debt of gratitude. Will they honour that debt and repay me by protecting me from Saul, and not letting him come into the city to take me?’ And the Lord answers, ‘They will not protect you; they will betray you and give you and your men up to Saul.’ David who had a profound understanding of the man’s behaviour obviously suspected this, or he would not have asked. It seemed an unlikely thing to happen. A naïve man might have thought that such a great act of deliverance would put the city under obligation to stand by David come what may. But no, their loyalty to him had its limits. They would serve self-interest when under pressure, despite the shame of ingratitude in doing so. The Lord answers David, with an answer of absolute certainty. He has middle knowledge. He knows what will actually happen, and he knows all possible future happenings. His knowledge is infinite. He has a plan and it is certain to come to pass, but he also knows what would happen if things were to take place differently. David hears this word from the Lord and receives it with complete assurance. If God says that the men of Keilah will betray him, then they will certainly do so.
