Now it was reported to David, “Look, the Philistines are fighting against Keilah and looting the threshing floors.” / So David inquired of the LORD, “Should 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 if we go to Keilah against the armies of the Philistines?”
