1 Samuel 30:9-13

So David left, he and the six hundred men who were with him, and they came to the brook Besor, where some who were left behind stayed.

But David pursued, he and four hundred men, for two hundred who were too exhausted to cross the brook Besor stayed 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 also gave him a slice of fig cake and two cakes of raisins, and he ate; then his spirit revived. For he had not eaten bread or drunk water for three days and three nights.

Then 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 abandoned me when I became sick three days ago.
