1 Samuel 23:2, 9-12

David asked the LORD, “Should I go and attack them?” “Yes, go and save Keilah,” the LORD told him.

But David learned of Saul’s plan and told Abiathar the priest to bring the ephod and ask the LORD what he should do. Then David prayed, “O LORD, God of Israel, I have heard that Saul is planning to come and destroy Keilah because I am here. Will the leaders of Keilah betray me to him? And will Saul actually come as I have heard? O LORD, God of Israel, please tell me.” And the LORD said, “He will come.” Again David asked, “Will the leaders of Keilah betray me and my men to Saul?” And the LORD replied, “Yes, they will betray you.”
