1 Samuel 30:12-13

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.

13Then David said to him, “To whom do you belong, and where are you from?” And he said, “I am a young man from Egypt, servant of an Amalekite; and my master left me behind, because three days ago I fell sick.
