Rav Naḥman bar Yitzḥak said: That which is hidden is hidden, and that which is revealed is revealed, but in Heaven everything is known, and the great court in Heaven will exact payment from those who wear the cloak of the righteous but are in fact unworthy.
בָּרוּךְ הַמָּקוֹם, בָּרוּךְ הוּא, בָּרוּךְ שֶׁנָּתַן תּוֹרָה לְעַמּוֹ יִשְׂרָאֵל, בָּרוּךְ הוּא. כְּנֶגֶד אַרְבָּעָה בָנִים דִּבְּרָה תוֹרָה: אֶחָד חָכָם, וְאֶחָד רָשָׁע, וְאֶחָד תָּם, וְאֶחָד שֶׁאֵינוֹ יוֹדֵעַ לִשְׁאוֹל.
חָכָם מָה הוּא אוֹמֵר? מָה הָעֵדוֹת וְהַחֻקִּים וְהַמִּשְׁפָּטִים אֲשֶׁר צִוָּה ה' אֱלֹהֵינוּ אֶתְכֶם. וְאַף אַתָּה אֱמוֹר לוֹ כְּהִלְכוֹת הַפֶּסַח: אֵין מַפְטִירִין אַחַר הַפֶּסַח אֲפִיקוֹמָאתִי מִמִּצְרָיִם.
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.' If he had been there, he would not have been saved."
