אַל־תִּֽירְאִי֙ כִּי־לֹ֣א תֵב֔וֹשִׁי וְאַל־תִּכָּלְמִ֖י כִּ֣י לֹ֣א תַחְפִּ֑ירִי כִּ֣י בֹ֤שֶׁת עֲלוּמַ֙יִךְ֙ תִּשְׁכָּ֔חִי וְחֶרְפַּ֥ת אַלְמְנוּתַ֖יִךְ לֹ֥א תִזְכְּרִי־עֽוֹד׃
No temas, que no serás avergonzada; y no te avergüences, que no serás afrentada: antes, te olvidarás de la vergüenza de tu mocedad, y de la afrenta de tu viudez no tendrás más memoria.
