ישעיהו, פרק מ״ב, פסוק י״ט

A profound spiritual contradiction often emerges where those closest to God are described as suffering from blindness and deafness. Rather than physical disabilities, these conditions represent different states of ignorance, lack of response, or a tragic gap between spiritual potential and reality. Commentators offer varying perspectives on who exactly is afflicted by this blindness and what it truly represents.

One approach suggests that this imagery reflects the scorn of the masses toward God's prophets. The people, who are the truly blind ones, point mockingly at the prophet and claim that no one is as blind and deaf as he is. In reality, however, the prophet possesses a complete and perfect vision of the heart [רד״ק, אבן עזרא, צאינה וראינה].

Conversely, other commentators explain that this blindness and deafness accurately describe the behavior of the righteous. A devoted servant of God may retreat into his own inner world, appearing entirely blind and deaf to the outside environment [ביאור שטיינזלץ]. He purposefully ignores his surroundings to avoid looking at the corruption and vanity of his generation. Yet, this approach is not entirely praised. His silence and refusal to correct the people are considered a deep flaw, which is why he earns the title of being blind [מצודת דוד, צוארי שלל].

Another perspective shifts the focus to the nation of Israel as a whole. The Israelites are called blind precisely because they possess all the natural and practical tools to experience spiritual vision through the Torah and its Commandments, yet they still fail to see [מלבי״ם]. Alternatively, this sensory deprivation describes the state of the Israelites in exile. They act as if they are deaf and blind, quietly enduring their oppression without rebelling against their captors, as though they cannot feel the harshness of their reality [שד״ל].

The individual sent by God as a messenger [מצודת ציון, אבן עזרא] is characterized by a unique sense of wholeness, though this perfection is understood in several ways. It can describe a person who is completely flawless in his character, wisdom, and spiritual traits [מצודת דוד, מלבי״ם, ביאור שטיינזלץ]. It can also refer to a righteous individual who is receiving his just reward [אבן עזרא], or one who has already paid his debt through suffering and emerged entirely clean from sin [רש״י]. Furthermore, it describes someone who has surrendered completely, dedicating his entire soul to serving God [שד״ל].

Ultimately, the repeated emphasis on the blindness of God's servant serves as a poetic device to strengthen the overall message [מצודת דוד, רד״ק]. It also broadens the scope of the lesson, indicating that these spiritual challenges apply to anyone who dedicates themselves to serving God, even if they do not reach the exalted level of a prophet [אבן עזרא].
