Commentary for Esther 8:8

וְ֠אַתֶּם כִּתְב֨וּ עַל־הַיְּהוּדִ֜ים כַּטּ֤וֹב בְּעֵֽינֵיכֶם֙ בְּשֵׁ֣ם הַמֶּ֔לֶךְ וְחִתְמ֖וּ בְּטַבַּ֣עַת הַמֶּ֑לֶךְ כִּֽי־כְתָ֞ב אֲשֶׁר־נִכְתָּ֣ב בְּשֵׁם־הַמֶּ֗לֶךְ וְנַחְתּ֛וֹם בְּטַבַּ֥עַת הַמֶּ֖לֶךְ אֵ֥ין לְהָשִֽׁיב׃

Write ye also concerning the Jews, as it liketh you, in the king’s name, and seal it with the king’s ring; for the writing which is written in the king’s name, and sealed with the king’s ring, may no man reverse.’
