1 Samuel 30:3

And behold, it was burned with fire. — A terrible reception for David and his free lances, on their return from their ill-omened expedition with the great Philistine army, to find only the charred and smoking ruins of their homes; not one of all their dear ones, whom they had left behind — as they thought in security — left to tell the story of the disaster. It was the Egyptian slave who had fallen sick, and, in consequence, had been deserted, and whom they came upon in the course of the pursuit, who gave them the details, and told them the story of the invasion, and described the route taken by the marauding force on their return to their country.
