1 Samuel 30:9-12

9So David went, he and the six hundred men that were with him, and they came to the torrent Besor; and those that were left stayed behind.

10And David pursued, he and four hundred men; for two hundred stayed behind, who were too exhausted to go over the torrent Besor.

11And they found an Egyptian in the field, and brought him to David, and gave him bread, and he ate; and they gave him water to drink,

12and gave him a piece of fig-cake and two raisin-cakes, and he ate, and his spirit came again to him; for he had eaten no bread, nor drunk any water, for three days and three nights.
