1 Samuel 30:17-20

17David slaughtered them from twilight until the evening of the next day. None of them escaped, except four hundred young men who got on camels and fled.

18David recovered everything the Amalekites had taken; he also rescued his two wives.

19Nothing of theirs was missing from the youngest to the oldest, including the sons and daughters, and all the plunder the Amalekites had taken. David got everything back.

20He took all the flocks and herds, which were driven ahead of the other livestock, and the people shouted, “This is David’s plunder!”
