They were also blind in another sense: although nothing impeded them from recognizing their Creator through the beauty of His creation, for, as Paul wisely states, His invisible attributes, understood through what has been made, are clearly visible, including His eternal power and divine nature (Rom. 1:20). Still, they sank into such folly that they proclaimed to the molded figures, "You are our gods." The prophet, however, addressed not the multitude of Gentiles but rather the descendants of Israel, emphasizing: "Who are blind but my servants? And who are deaf but those who are my messengers?" As a result, the people they led became blind, suffering significantly due to the negligence of their leaders; they themselves were responsible for their ignorance and taught error. The foolish ones were indeed the rulers they followed, who, despite having witnessed the glory of God and having been partakers of His grace, chose rebellion and refused to obey God’s clear command: "You shall have no other gods before Me" (Ex. 20:3).
Thus, knowing well the divine revelations but turning away alongside their followers, the prophet expresses his astonishment, saying, "The servants of God are blinded." What caused their blindness? The prophet answers, "You brought this upon yourselves," emphasizing that they had the opportunity to remain vigilant, often witnessing the glory of God, and hearing, knowing, and understanding His written word. Yet they did not guard against neglecting it, nor did they show diligence in deepening their understanding of the sacred laws. Therefore, the sins of the Jews are not justifiable; although they had the truth available to them, guided by the law, they acted as if they were blind and deaf, ignoring the divine commandments due to their unwillingness to heed the truth.
