וְכָל־הָעֵ֣מֶק הַפְּגָרִ֣ים ׀ וְהַדֶּ֡שֶׁן וְכָֽל־השרמות [הַשְּׁדֵמוֹת֩] עַד־נַ֨חַל קִדְר֜וֹן עַד־פִּנַּ֨ת שַׁ֤עַר הַסּוּסִים֙ מִזְרָ֔חָה קֹ֖דֶשׁ לַֽיהוָ֑ה לֹֽא־יִנָּתֵ֧שׁ וְֽלֹא־יֵהָרֵ֛ס ע֖וֹד לְעוֹלָֽם׃ (ס)
And the whole valley of the dead bodies, and of the ashes, and all the fields unto the brook Kidron, unto the corner of the horse gate toward the east, shall be holy unto the LORD; it shall not be plucked up, nor thrown down any more for ever.
