I Samuel 23:1-3

Then they told David, saying, “Look, the Philistines are fighting against Keilah, and they are robbing the threshing floors.” Therefore 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 save Keilah.” But David’s men said to him, “Look, we are afraid here in Judah. How much more then if we go to Keilah against the armies of the Philistines?”
