וְאַחֲרֵי־כֵ֥ן נִגְּשׁ֖וּ כָּל־בְּנֵ֣י יִשְׂרָאֵ֑ל וַיְצַוֵּ֕ם אֵת֩ כָּל־אֲשֶׁ֨ר דִּבֶּ֧ר יְהוָ֛ה אִתּ֖וֹ בְּהַ֥ר סִינָֽי׃
그 후에야 온 이스라엘 자손이 가까이 오는지라 모세가 여호와께서 시내 산에서 자기에게 이르신 말씀을 다 그들에게 명하고

"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."
