וְאַחֲרֵי־כֵ֥ן נִגְּשׁ֖וּ כָּל־בְּנֵ֣י יִשְׂרָאֵ֑ל וַיְצַוֵּ֕ם אֵת֩ כָּל־אֲשֶׁ֨ר דִּבֶּ֧ר יְהוָ֛ה אִתּ֖וֹ בְּהַ֥ר סִינָֽי׃
Sesudah itu, semua orang Israel datang mendekat, lalu ia memerintahkan kepada mereka segala sesuatu yang telah difirmankan Yang Mahakekal kepadanya di Gunung Sinai.
Mekhilta DeRabbi Yishmael
"This month": Nissan. You say it is Nissan. But perhaps it was some other month of the year? It is written (Exodus 23:16) "And the festival of the ingathering (Succoth) at the end of the year," (Ibid. 34:22) "And the festival of the ingathering at the turn of the year." In which month is there ingathering and turning (from one solstice to another) and the expiration of a year? Tishrei. After learning that the seventh month is Tishrei, we infer that the first month is Nissan. And even though there is no proof for this, it is intimated in (Esther 3:7) "In the first month, the month of Nissan."
