בַּיּ֣וֹם הַה֡וּא יִפְקֹ֣ד יְהוָה֩ בְּחַרְב֨וֹ הַקָּשָׁ֜ה וְהַגְּדוֹלָ֣ה וְהַֽחֲזָקָ֗ה עַ֤ל לִוְיָתָן֙ נָחָ֣שׁ בָּרִ֔חַ וְעַל֙ לִוְיָתָ֔ן נָחָ֖שׁ עֲקַלָּת֑וֹן וְהָרַ֥ג אֶת־הַתַּנִּ֖ין אֲשֶׁ֥ר בַּיָּֽם׃ (ס)
In that day the LORD with his sore and great and strong sword will punish leviathan the slant serpent, and leviathan the tortuous serpent; and He will slay the dragon that is in the sea.
