Quotation do Koheleta 12:1
וּזְכֹר֙ אֶת־בּ֣וֹרְאֶ֔יךָ בִּימֵ֖י בְּחוּרֹתֶ֑יךָ עַ֣ד אֲשֶׁ֤ר לֹא־יָבֹ֙אוּ֙ יְמֵ֣י הָֽרָעָ֔ה וְהִגִּ֣יעוּ שָׁנִ֔ים אֲשֶׁ֣ר תֹּאמַ֔ר אֵֽין־לִ֥י בָהֶ֖ם חֵֽפֶץ׃
Pamiętaj tedy o Stwórcy swoim w dniach młodzieńczych twoich, zanim nadejdą dni złowrogie, a zbliżą się lata, o których powiesz: nie mam upodobania w nich.

Circumcision is performed on the eighth day, the Torah was received on the 50th day following Pesach which is the day following seven weeks of seven days, the miracle of Hanukah lasted eight days.
