וְהָֽפַכְתִּי֙ כִּסֵּ֣א מַמְלָכ֔וֹת וְהִ֨שְׁמַדְתִּ֔י חֹ֖זֶק מַמְלְכ֣וֹת הַגּוֹיִ֑ם וְהָפַכְתִּ֤י מֶרְכָּבָה֙ וְרֹ֣כְבֶ֔יהָ וְיָרְד֤וּ סוּסִים֙ וְרֹ֣כְבֵיהֶ֔ם אִ֖ישׁ בְּחֶ֥רֶב אָחִֽיו׃
and I will overthrow the throne of kingdoms, and I will destroy the strength of the kingdoms of the nations; and I will overthrow the chariots, and those that ride in them; and the horses and their riders shall come down, every one by the sword of his brother.
