1 Samuel 30:11-19

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; 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. 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. We made a raid upon the South of the Cherethites, and upon that which belongeth to Judah, and upon the South of Caleb; and we burned Ziklag with fire. And David said to him, Wilt thou bring me down to this troop? And he said, Swear unto me by God, that thou wilt neither kill me, nor deliver me up into the hands of my master, and I will bring thee down to this troop. And when he had brought him down, behold, they were spread abroad over all the ground, eating and drinking, and dancing, because of all the great spoil that they had taken out of the land of the Philistines, and out of the land of Judah. And David smote them from the twilight even unto the evening of the next day: and there escaped not a man of them, save four hundred young men, who rode upon camels and fled. And David recovered all that the Amalekites had taken; and David rescued his two wives. And there was nothing lacking to them, neither small nor great, neither sons nor daughters, neither spoil, nor anything that they had taken to them: David brought back all.
