1 Samuel 30:11-15

11They found an Egyptian [who had collapsed] in the field and brought him to David, and gave him bread and he ate, and they gave him water to drink,

12and they gave him a piece of a fig cake and two clusters of raisins; and when he had eaten, his energy returned, for he had not eaten bread or had any water to drink for three days and three nights.

13David said to him, “To whom do you belong, and where are you from?” He said, “I am a young man from Egypt, a servant of an Amalekite; and my master abandoned me [as useless] when I fell sick three days ago.

14We made a raid on the Negev of the Cherethites, and on that which belongs to Judah, and on the Negev of Caleb, and we burned Ziklag with fire.”

15Then David said to him, “Will you take me down to this band [of raiders]?” And he said, “Swear to me by God that you will not kill me or turn me over to the hand of my master, and I will bring you down to this band.”
