וְאָר֣וּר נוֹכֵ֗ל וְיֵ֤שׁ בְּעֶדְרוֹ֙ זָכָ֔ר וְנֹדֵ֛ר וְזֹבֵ֥חַ מָשְׁחָ֖ת לַֽאדֹנָ֑י כִּי֩ מֶ֨לֶךְ גָּד֜וֹל אָ֗נִי אָמַר֙ יְהוָ֣ה צְבָא֔וֹת וּשְׁמִ֖י נוֹרָ֥א בַגּוֹיִֽם׃
But cursed be he that dealeth craftily, Whereas he hath in his flock a male, And voweth, and sacrificeth unto the Lord a blemished thing; For I am a great King, Saith the LORD of hosts, And My name is feared among the nations.
