וְאִם־מִשְׁפַּ֨חַת מִצְרַ֧יִם לֹֽא־תַעֲלֶ֛ה וְלֹ֥א בָאָ֖ה וְלֹ֣א עֲלֵיהֶ֑ם תִּֽהְיֶ֣ה הַמַּגֵּפָ֗ה אֲשֶׁ֨ר יִגֹּ֤ף יְהוָה֙ אֶת־הַגּוֹיִ֔ם אֲשֶׁר֙ לֹ֣א יַֽעֲל֔וּ לָחֹ֖ג אֶת־חַ֥ג הַסֻּכּֽוֹת׃
And if the family of Egypt go not up, and come not, they shall have no overflow; there shall be the plague, wherewith the LORD will smite the nations that go not up to keep the feast of tabernacles.
