John Gill's Exposition of the Bible
Isaiah 29:10

For the Lord hath poured out upon you a spirit of deep
sleep
Gave them up to a stupid frame of spirit; to a reprobate mind, a mind void of judgment and sense; to judicial blindness and hardness of heart: this was remarkably fulfilled in the Jews, in the times of Christ and his apostles, who choosing darkness rather than the light of the Gospel, which shone around them, were righteously given up to such a temper of mind; and to nothing else can be imputed their obstinate rejection of the Messiah, against the most glaring light and evidence. The Apostle Paul produces this passage, in proof of that blindness that had happened unto them in his time, ( Romans 11:7 Romans 11:8 ) : and hath closed your eyes;
that is, the eyes of their understandings, so that they could not see the characters of the Messiah, and the fulfilment of prophecies in Jesus of Nazareth; nor the danger they were in, nor the ruin that was coming upon their nation, nor even when it was come, still flattering themselves with safety and deliverance: the prophets and your rulers, the seers hath he covered;
the eyes of them, as before; not only the common people were blinded, but even the Scribes and Pharisees, the elders of the people, their ecclesiastical rulers, who pretended to be seers, and to know more than others; even "for judgment", for the judicial blindness and hardness of these Christ "came, that they which see might be made blind", ( John 9:39 ) . The words may be rendered, "your heads, the seers, hath he covered" F20; and there may be an allusion to the covering of the head with a veil, an emblem of that veil of ignorance and infidelity which still remains upon the Jews. The Targum renders it,

``the prophets, and the Scribes, and the teachers that teach the law.''
