1 Samuel 30:11 KJV

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

10But David pursued, he and four hundred men: for two hundred abode behind, which were so faint that they could not go over the brook Besor.

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

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

13And David said unto him, To whom belongest thou? and whence art thou? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days agone I fell sick.
