1 Samuel 30:9-12

9So 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.

10But David pursued, he and four hundred men. Two hundred stayed behind, who were too exhausted to cross the brook Besor.

11They 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,

12and 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.
