Halakhah su Esodo 12:26

What does the evil [son] say? "'What is this worship to you?' (Exodus 12:26)" 'To you' and not 'to him.' And since he excluded himself from the collective, he denied a principle [of the Jewish faith]. And accordingly, you will blunt his teeth and say to him, "'For the sake of this did the Lord do [this] for me in my going out of Egypt' (Exodus 13:8)." 'For me' and not 'for him.' And if he had been there, he would not have been saved.
