1 Samuel 30:9-12

9So David went, he and the six hundred men who were with him, and came to the Brook Besor, where those stayed who were left behind.

10But David pursued, he and four hundred men; for two hundred stayed behind, who were so weary that they could not cross the Brook Besor.

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

12And they gave him a piece of a cake of figs and two clusters of raisins. So when he had eaten, his strength came back to him; for he had eaten no bread nor drunk water for three days and three nights.
