1 Samuel 30:11 ASV

⁹  So 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.

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

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

¹²  And 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.

¹³  And 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 ago I fell sick.
