בָּעֵת֩ הַהִ֨יא יֽוּבַל־שַׁ֜י לַיהוָ֣ה צְבָא֗וֹת עַ֚ם מְמֻשָּׁ֣ךְ וּמוֹרָ֔ט וּמֵעַ֥ם נוֹרָ֖א מִן־ה֣וּא וָהָ֑לְאָה גּ֣וֹי ׀ קַו־קָ֣ו וּמְבוּסָ֗ה אֲשֶׁ֨ר בָּזְא֤וּ נְהָרִים֙ אַרְצ֔וֹ אֶל־מְק֛וֹם שֵׁם־יְהוָ֥ה צְבָא֖וֹת הַר־צִיּֽוֹן׃ (ס)
In that time shall a present be brought unto the LORD of hosts of a people tall and of glossy skin, and from a people terrible from their beginning onward; a nation that is sturdy and treadeth down, whose land the rivers divide, to the place of the name of the LORD of hosts, the mount Zion.
