Corresponding to four children did the Torah speak; one [who is] wise, one [who is] evil, one who is innocent and one who doesn't know to ask.
What does the wise one say? "'What are these testimonies, statutes and judgments that the Lord our God commanded you?' (Deuteronomy 6:20)" And accordingly you will respond, as per the laws of the Pesach sacrifice, "We may not eat an afikoman [a dessert or other foods eaten after the meal] after [we are finished eating] the Pesach sacrifice (Mishnah Pesachim 10:8)."
What does the evil one say? "'What is this worship to you?' (Exodus 12:26)" 'To you' and not 'to him.' And since s/he excluded themself from the collective, s/he denied a principle [of the Jewish faith]. And accordingly, you will blunt their teeth and say to them, "'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 them.' If s/he had been there, s/he would not have been saved.
What does the innocent one say? "'What is this?' (Exodus 13:14)" And you will respond, "'With the strength of [God's] hand did the Lord take us out from Egypt, from the house of slaves' (Exodus 13:14).'"
And [regarding] the one who doesn't know to ask, you will open [the conversation] . As it is stated (Exodus 13:8), "And you will speak to your child on that day saying, for the sake of this, did the Lord do [this] for me in my going out of Egypt."
