1 Samuel 30:11-19

They found an Egyptian in a field and brought him to David. They gave the Egyptian some water to drink and some food to eat. And they gave him a piece of a fig cake and two clusters of raisins. Then he felt better, because he had not eaten any food or drunk any water for three days and nights. David asked him, “Who is your master? Where do you come from?” He answered, “I’m an Egyptian, the slave of an Amalekite. Three days ago my master left me, because I was sick. We had raided the southern area of the Kerethites, the land of Judah, and the southern area of Caleb. We burned Ziklag, as well.” David asked him, “Can you lead me to the people who took our families?” He answered, “Yes, if you promise me before God that you won’t kill me or give me back to my master. Then I will take you to them.” So the Egyptian led David to the Amalekites. They were lying around on the ground, eating and drinking and celebrating with the things they had taken from the land of the Philistines and from Judah. David fought them from sunset until the evening of the next day. None of them escaped, except four hundred young men who rode off on their camels. David got his two wives back and everything the Amalekites had taken. Nothing was missing. David brought back everyone, young and old, sons and daughters. He recovered the valuable things and everything the Amalekites had taken.
