1 Samuel 30:16-20

When he brought David down, the Amalekites had disbanded and spread over all the land, eating and drinking and dancing because of all the great spoil they had taken from the land of the Philistines and from the land of Judah. Then David [and his men] struck them down [in battle] from twilight until the evening of the next day; and not a man of them escaped, except four hundred young men who rode camels and fled. So David recovered all that the Amalekites had taken, and rescued his two wives. Nothing of theirs was missing whether small or great, sons or daughters, spoil or anything that had been taken; David recovered it all. So David captured all the flocks and herds [which the enemy had], and [the people] drove those animals before him and said, “This is David’s spoil.”
