1 Samuel 30:17-20

David and his men rushed in among them and slaughtered them throughout that night and the entire next day until evening. None of the Amalekites escaped except 400 young men who fled on camels. David got back everything the Amalekites had taken, and he rescued his two wives. Nothing was missing: small or great, son or daughter, nor anything else that had been taken. David brought everything back. He also recovered all the flocks and herds, and his men drove them ahead of the other livestock. “This plunder belongs to David!” they said.
