1 Samuel 23:1-3

Then they informed David, saying, “Behold, the Philistines are fighting against Keilah and are plundering the threshing floors.”

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 save Keilah.”

But David’s men said to him, “Behold, we are fearful here in Judah. How much more then if we go to Keilah against the ranks of the Philistines?”
