II Kings 19:4 Halakhah

אוּלַ֡י יִשְׁמַע֩ יְהוָ֨ה אֱלֹהֶ֜יךָ אֵ֣ת ׀ כָּל־דִּבְרֵ֣י רַב־שָׁקֵ֗ה אֲשֶׁר֩ שְׁלָח֨וֹ מֶֽלֶךְ־אַשּׁ֤וּר ׀ אֲדֹנָיו֙ לְחָרֵף֙ אֱלֹהִ֣ים חַ֔י וְהוֹכִ֙יחַ֙ בַּדְּבָרִ֔ים אֲשֶׁ֥ר שָׁמַ֖ע יְהוָ֣ה אֱלֹהֶ֑יךָ וְנָשָׂ֣אתָ תְפִלָּ֔ה בְּעַ֥ד הַשְּׁאֵרִ֖ית הַנִּמְצָאָֽה׃

Perhaps the Lord your God will hear all the words of Ravshakeh, whom his lord, the King of Assyria, has sent to blaspheme the living God, and your God has heard how he argued, and you shall offer a prayer for the remainder that is found.
