Targum for Isaiah 6:5

וָאֹמַ֞ר אֽוֹי־לִ֣י כִֽי־נִדְמֵ֗יתִי כִּ֣י אִ֤ישׁ טְמֵֽא־שְׂפָתַ֙יִם֙ אָנֹ֔כִי וּבְתוֹךְ֙ עַם־טְמֵ֣א שְׂפָתַ֔יִם אָנֹכִ֖י יוֹשֵׁ֑ב כִּ֗י אֶת־הַמֶּ֛לֶךְ יְהוָ֥ה צְבָא֖וֹת רָא֥וּ עֵינָֽי׃

Then said I: Woe is me! for I am undone; Because I am a man of unclean lips, And I dwell in the midst of a people of unclean lips; For mine eyes have seen the King, The LORD of hosts.
