1 Samuel 30:9-16

So David set out, and the six hundred men who were with him, and they came to the brook Besor, where those who were left behind stayed. But David pursued, he and four hundred men. Two hundred stayed behind, who were too exhausted to cross the brook Besor. They found an Egyptian in the open country and brought him to David. And they gave him bread and he ate. They gave him water to drink, and they gave him a piece of a cake of figs and two clusters of raisins. And when he had eaten, his spirit revived, for he had not eaten bread or drunk water for three days and three nights. And David said to him, “To whom do you belong? And where are you from?” He said, “I am a young man of Egypt, servant to an Amalekite, and my master left me behind because I fell sick three days ago. We had made a raid against the Negeb of the Cherethites and against that which belongs to Judah and against the Negeb of Caleb, and we burned Ziklag with fire.” And David said to him, “Will you take 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 take you down to this band.” And when he had taken him down, behold, they were spread abroad over all the land, eating and drinking and dancing, because of all the great spoil they had taken from the land of the Philistines and from the land of Judah.
