1 Samuel 30:11-15
30:11 Then they found an Egyptian in the field and brought him to David. They gave him bread to eat and water to drink.
30:12 They gave him a slice of pressed figs and two bunches of raisins to eat. This greatly refreshed him, for he had not eaten food or drunk water for three days and three nights.
30:13 David said to him, “To whom do you belong, and where are you from?” The young man said, “I am an Egyptian, the servant of an Amalekite man. My master abandoned me when I was ill for three days.
30:14 We conducted a raid on the Negev of the Kerethites, on the area of Judah, and on the Negev of Caleb. We burned Ziklag.”
30:15 David said to him, “Can you take us down to this raiding party?” He said, “Swear to me by God that you will not kill me or hand me over to my master, and I will take you down to this raiding party.”
