1 Samuel 30:11-16

Along the way they found an Egyptian man in a field and brought him to David. They gave him some bread to eat and water to drink. They also gave him part of a fig cake and two clusters of raisins, for he hadn’t had anything to eat or drink for three days and nights. Before long his strength returned. “To whom do you belong, and where do you come from?” David asked him. “I am an Egyptian—the slave of an Amalekite,” he replied. “My master abandoned me three days ago because I was sick. We were on our way back from raiding the Kerethites in the Negev, the territory of Judah, and the land of Caleb, and we had just burned Ziklag.” “Will you lead me to this band of raiders?” David asked. The young man replied, “If you take an oath in God’s name that you will not kill me or give me back to my master, then I will guide you to them.” So he led David to them, and they found the Amalekites spread out across the fields, eating and drinking and dancing with joy because of the vast amount of plunder they had taken from the Philistines and the land of Judah.
