וְהָיִ֜יתָ מְמַשֵּׁ֣שׁ בַּֽצָּהֳרַ֗יִם כַּאֲשֶׁ֨ר יְמַשֵּׁ֤שׁ הָעִוֵּר֙ בָּאֲפֵלָ֔ה וְלֹ֥א תַצְלִ֖יחַ אֶת־דְּרָכֶ֑יךָ וְהָיִ֜יתָ אַ֣ךְ עָשׁ֧וּק וְגָז֛וּל כָּל־הַיָּמִ֖ים וְאֵ֥ין מוֹשִֽׁיעַ׃
et tu iras tâtonnant en plein midi comme fait l’aveugle dans les ténèbres, tu ne mèneras pas à bonne fin tes entreprises, tu seras opprimé et spolié incessamment, sans trouver un défenseur.
Rashi
עשוק [THOU SHALT BE] WRONGED — i.e. against every action of yours there will be dispute.

כאשר ימשש העור באפלה, “as the blind gropes in the darkness.” He does so out of fear. If he felt that he was in an area that was lit up, there would be people who would assist him, or at least warn him of obstacles in his way. (Talmud Megillah, 24)
Ibn Ezra
you will grope Scripture elaborates on the abovementioned “blindness” [: 28].
