וְכִֽי־תַגִּשׁ֨וּן עִוֵּ֤ר לִזְבֹּ֙חַ֙ אֵ֣ין רָ֔ע וְכִ֥י תַגִּ֛ישׁוּ פִּסֵּ֥חַ וְחֹלֶ֖ה אֵ֣ין רָ֑ע הַקְרִיבֵ֨הוּ נָ֜א לְפֶחָתֶ֗ךָ הֲיִּרְצְךָ֙ א֚וֹ הֲיִשָּׂ֣א פָנֶ֔יךָ אָמַ֖ר יְהוָ֥ה צְבָאֽוֹת׃
And when ye offer the blind for sacrifice, is it no evil! And when ye offer the lame and sick, is it no evil! Present it now unto thy governor; will he be pleased with thee? Or will he accept thy person? Saith the LORD of hosts.
