1 Samuel 30:10

7 And David said to Abiathar the priest, Ahimelech’s son, I pray thee, bring me hither the ephod. And Abiathar brought thither the ephod to David.

8 And David inquired at the LORD, saying, Shall I pursue after this troop? shall I overtake them? And he answered him, Pursue: for thou shalt surely overtake [them], and without fail recover [all].

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 abode behind, which 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 made him drink water;

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 agone I fell sick.
