1 Samuel 30:9-16

So David went, he and the six hundred men who were with him, and came to the brook Besor, where those left behind remained. But David pursued, he and four hundred men, for two hundred who were too exhausted to cross the brook Besor remained behind. Now they found an Egyptian in the field and brought him to David, and gave him bread and he ate, and they provided him water to drink. They gave him a piece of fig cake and two clusters of raisins, and he ate; then his spirit revived. For he had not eaten bread or drunk water for three days and three nights. David said to him, “To whom do you belong? And where are you from?” And he said, “I am a young man of Egypt, a servant of an Amalekite; and my master left me behind when I fell sick three days ago. We made a raid on the Negev of the Cherethites, and on that which belongs to Judah, and on the Negev of Caleb, and we burned Ziklag with fire.” Then David said to him, “Will you bring me down to this band?” And he said, “Swear to me by God that you will not kill me or deliver me into the hands of my master, and I will bring you down to this band.” When he had brought him down, behold, they were spread over all the land, eating and drinking and dancing because of all the great spoil that they had taken from the land of the Philistines and from the land of Judah.
