וְאָשִׁ֤יבָה שֹׁפְטַ֙יִךְ֙ כְּבָרִ֣אשֹׁנָ֔ה וְיֹעֲצַ֖יִךְ כְּבַתְּחִלָּ֑ה אַחֲרֵי־כֵ֗ן יִקָּ֤רֵא לָךְ֙ עִ֣יר הַצֶּ֔דֶק קִרְיָ֖ה נֶאֱמָנָֽה׃
And I will restore thy judges as at the first, And thy counsellors as at the beginning; Afterward thou shalt be called The city of righteousness, The faithful city.
