시편 146:8 해설: Radak & Ibn Ezra

ה' פוקח עורים. "The Lord opens the eyes of the blind": Those who are blind from an eye disease, He will heal them. This ailment is mentioned because blindness, like imprisonment, prevents a person from moving from their place. Alternatively, it can mean those blinded by extreme distress, as suffering is likened to darkness and salvation to light. There are many verses in Scripture that attest to this. Similarly, He did for Israel, who were blinded in exile, as it is said, "We grope for the wall like the blind, and we grope as if we had no eyes; we stumble at noonday as in the night."

"God" - See here that the meaning is [that] it is not appropriate that a man lean on another man and if a man is to be strengthened from him, [it should be that] he leans on him in his prayer to God(i.e. the man is a conduit for salvation which is requested in prayer to God), and so too if he is hungry or he is imprisoned [he will be saved], and so too if he gets an affliction of the eyes, or he was continually forced to stay in bed [because of sickness], he should not lean on a doctor.

ה' זוקף כפופים. "The Lord raises those who are bowed down":, meaning the poor, as we have explained.
