וְהָיִ֜יתָ מְמַשֵּׁ֣שׁ בַּֽצָּהֳרַ֗יִם כַּאֲשֶׁ֨ר יְמַשֵּׁ֤שׁ הָעִוֵּר֙ בָּאֲפֵלָ֔ה וְלֹ֥א תַצְלִ֖יחַ אֶת־דְּרָכֶ֑יךָ וְהָיִ֜יתָ אַ֣ךְ עָשׁ֧וּק וְגָז֛וּל כָּל־הַיָּמִ֖ים וְאֵ֥ין מוֹשִֽׁיעַ׃
And thou shalt grope at noonday, as the blind gropeth in darkness, and thou shalt not make thy ways prosperous; and thou shalt be only oppressed and robbed alway, and there shall be none to save thee.
