Samson said to them, This time shall I be blameless in regard of the Philistines, when I do them a mischief.
He already of course paid the dowry and everything else and so he said, "You know her beautiful, young sister, why don't you take her?" But Samson was sort of a hothead. He didn't appreciate the fact that his father-in-law giving his bride away. And so he decided to get even with the Philistines because they were the ones who sort of set the whole thing up anyhow; getting the secret out of his bride and they ruined this whole escapade.
