1 Samuel 30:16-17

When he had brought him down, behold, they were spread over all the land, eating and drinking and dancing because of all the great spoil that they had taken from the land of the Philistines and from the land of Judah. David slaughtered them from the twilight until the evening of the next day; and not a man of them escaped, except four hundred young men who rode on camels and fled.
