Isaiah 29:12 cannot be Jesus(pbuh) as it describes someone unlettered like the Prophet Muhammad(s.a.w)
Isaiah 29:12-14 King James Version (KJV)
12 And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.
13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
14 Therefore, behold, I will proceed to do a marvellous work among this people, even a marvellous work and a wonder: for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid.
