Isaiah 53 describes a suffering Messiah. Didn't see because they did not want to see. The OT also states that cursed is the man who is hung on a tree.
De 21:22 And if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree:
Ga 3:13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:
For the cause of Christ

Yes, we can see that now because we have the rest of the story. At times, the prophets spoke of things they themselves did not understand.
