It turns out that [the Torah] has four sons: a smart son, a  stupid son, a wicked son, and one who does not know how  to ask.
	The wise son, what does he say? “What are the testimonies, statutes…?” (Deut 6:20) So you should open for him the laws of Pesah. Say to him: “[After eating] the Paschal lamb, one does not follow up with reveling (or ‘dessert’).”
	The stupid son, “saying ‘What is this?’ And you should say to him: ‘With a strong hand God took us out of Egypt’” (Exod 13:14).
	The wicked son says: “What is this service to you?” (Exod 12:26) Since he excluded himself from the whole you should exclude him from the whole. Say to him, “‘because of what God did for me’ (Exod 13:8)—me and not you, if you had been there, you would not have been redeemed.”
	And the one who doesn’t know to ask: you open with him, as it says, “you shall tell you son, etc.” (Exod 13:8)
