Luke 22:63-65 (KJV) And the men that held Jesus mocked him, and smote him. 64 And when they had blindfolded him, they struck him on the face, and asked him, saying, Prophesy, who is it that smote thee? 65 And many other things blasphemously spake they against him.
It is hard to imagine in our humanity how men like this can be forgiven for what they did to the Lord Jesus Christ, but the Bible says that even these men can have forgiveness:
Matthew 12:32 (KJV) And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
