The nounחרש (deaf and mute person) refers to two things, not hearing and not speaking.

And moreover, the noun עור (blind person) refers to two things, blindness of the eye and blindness of the heart. And opposite blindness of the heart comes the verb פקח (open). And thus, the phraseעור עיניו (blind in his eyes) is used several times to exclude blindness of the heart.

And the nounעור (blind person) also includes blindness in one eye. And moreover, the nounפסח (cripple) – can also mean cripple on one foot; unless it explains: את עיני צדקיהו עור (and put out the eyes of Zedekiah)⁷²¹, והוא פסח על שתי רגליו (and he was lame on both his feet)⁷²².

footnotes: ⁷²¹ 2 Kings 25:7. ⁷²² 2 Samuel 9:13.

והצולע (lame) - his thigh was collapsed, and he goes on one limp. And a פסח skips. And both can also be from birth. But נכה רגלים (crippled legs) is precisely through being beaten.
