וְאִם־מִשְׁפַּ֨חַת מִצְרַ֧יִם לֹֽא־תַעֲלֶ֛ה וְלֹ֥א בָאָ֖ה וְלֹ֣א עֲלֵיהֶ֑ם תִּֽהְיֶ֣ה הַמַּגֵּפָ֗ה אֲשֶׁ֨ר יִגֹּ֤ף יְהוָה֙ אֶת־הַגּוֹיִ֔ם אֲשֶׁר֙ לֹ֣א יַֽעֲל֔וּ לָחֹ֖ג אֶת־חַ֥ג הַסֻּכּֽוֹת׃
만일 애굽 족속이 올라오지 아니할 때에는 창일함이 있지 아니하리니 여호와께서 초막절을 지키러 올라오지 아니하는 열국 사람을 치시는 재앙을 그에게 내리실 것이라
Tze'enah Ure'enah
“If the community of Egypt does not ascend, etc.” [14:18]. That is, when the Egyptians will not go up to Jerusalem on Sukkot, what kind of travails should I impose on them when they never need rain? Their grain grows without rain. Therefore, I will punish them because they did not go up to Jerusalem and so will it happen to all the nations.
Rashi
And if the family of Egypt does not go up and they do not require rain, for the Nile comes up and waters it [i.e., the land of Egypt].
Rashi
it shall not [rain] upon them Their rain shall not be upon them; i.e., the Nile will not water them, and so did Jonathan render: The Nile shall not ascend upon them.
Rashi
with which the Lord will plague This will be the punishment of Egypt and the punishment of all the nations, as He states. “upon them there shall be no rain.”
