9 But David got wind of Saul's strategy to destroy him and said to Abiathar the priest, "Get the Ephod." 10 Then David prayed to God: "God of Israel, I've just heard that Saul plans to come to Keilah and destroy the city because of me. 11 Will the city fathers of Keilah turn me over to him? Will Saul come down and do what I've heard? O God, God of Israel, tell me!" God replied, "He's coming down." 12 "And will the head men of Keilah turn me and my men over to Saul?" And God said, "They'll turn you over." 13 So David and his men got out of there. There were about six hundred of them. They left Keilah and kept moving, going here, there, wherever - always on the move. When Saul was told that David had escaped from Keilah, he called off the raid.

(Read 1 Samuel 23:7-13)
Well might David complain of his enemies, that they rewarded him evil for good, and that for his love they were his adversaries. Christ was used thus basely. David applied to his great Protector for direction. No sooner was the ephod brought him than he made use of it. We have the Scriptures in our hands, let us take advice from them in doubtful cases. Say, Bring hither the Bible. David's address to God is very solemn, also very particular. God allows us to be so in our addresses to him; Lord, direct me in this matter, about which I am now at a loss. God knows not only what will be, but what would be, if it were not hindered; therefore he knows how to deliver the godly out of temptation, and how to render to every man according to his works.
