6 Now it happened, when Abiathar the son of Ahimelech fled to David at Keilah, that he went down with an ephod in his hand.

7 And Saul was told that David had gone to Keilah. So Saul said, "God has delivered him into my hand, for he has shut himself in by entering a town that has gates and bars." 8 Then Saul called all the people together for war, to go down to Keilah to besiege David and his men. 9 When David knew that Saul plotted evil against him, he said to Abiathar the priest, "Bring the ephod here." 10 Then David said, "O Lord God of Israel, Your servant has certainly heard that Saul seeks to come to Keilah to destroy the city for my sake. 11 Will the men of Keilah deliver me into his hand? Will Saul come down, as Your servant has heard? O Lord God of Israel, I pray, tell Your servant." And the Lord said, "He will come down." 12 Then David said, "Will the men of Keilah deliver me and my men into the hand of Saul?" And the Lord said, "They will deliver you."

Matthew Henry's Commentary on 1 Samuel 23:6-12

Commentary on 1 Samuel 23:1-6

(Read 1 Samuel 23:1-6)

When princes persecute God's people, let them expect vexation on all sides. The way for any country to be quiet, is to let God's church be quiet in it: if Saul fight against David, the Philistines fight against his country. David considered himself the protector of the land. Thus did the Saviour Jesus, and left us an example. Those are unlike David, who sullenly decline to do good, if they are not rewarded for services.

Commentary on 1 Samuel 23:7-13

(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.
