1 Samuel 23:2, 9-12

So David inquired of the LORD, saying, “Shall I go and attack these Philistines?” And the LORD said to David, “Go and attack the Philistines and deliver Keilah.”

Now David knew that Saul was plotting evil against him; so he said to Abiathar the priest, “Bring the ephod here.” Then David said, “O LORD God of Israel, Your servant has heard for certain that Saul is seeking to come to Keilah to destroy the city on my account. Will the men of Keilah surrender me into his hand? Will Saul come down just as Your servant has heard? O LORD God of Israel, I pray, tell Your servant.” And the LORD said, “He will come down.” Then David said, “Will the men of Keilah surrender me and my men into the hand of Saul?” And the LORD said, “They will surrender you.”
