כִּ֛י גַּם־פְּעָמִ֥ים רַבּ֖וֹת יָדַ֣ע לִבֶּ֑ךָ אֲשֶׁ֥ר גַּם־את [אַתָּ֖ה] קִלַּ֥לְתָּ אֲחֵרִֽים׃
Sebab hatimu sendiri tahu bahwa engkau pun telah berkali-kali mengutuki orang lain.
Barukh SheAmar
As for the one who does not know to ask, you begin for him: There are a number of places in the Bible where the feminine form of “you - aht” is used in place of the masculine “you - ahtah.” See numbers 11:15, Deuteronomy 5:24, Ecclesiastes 7:22 and Ezekiel 28:14. In each case the sages see this as an opportunity for a Drash. Rabbi Epstein understands this as a hint that for this child even the words of the verse are not enough to teach him the full significance of the Seder. Begin with “Aht” - everything from “Aleph” though “Tauf,” the first and last letters of the “Aleph-Bet.”
