I Samuel 30:17-20

Then David attacked them from twilight until the evening of the next day. Not a man of them escaped, except four hundred young men who rode on camels and fled. So David recovered all that the Amalekites had carried away, and David rescued his two wives. And nothing of theirs was lacking, either small or great, sons or daughters, spoil or anything which they had taken from them; David recovered all. Then David took all the flocks and herds they had driven before those other livestock, and said, “This is David’s spoil.”
