What is the hope of the godless when God cuts him off

Job 27:1-23
As God lives, who has taken away my right, and the Almighty, who has made my soul bitter.
Far be it from me to say that you are right; till I die I will not put away my integrity from me. I hold fast my righteousness and will not let it go;
For what is the hope of the godless when God cuts him off.
His friends want him to deny his integrity, but Job will not perjure himself.
V 13-23 sound strange coming from Job. This has previously been the argument his friends have put forward. Either Job's thinking has changed, or this passage really belongs to one of the others.
Why?
Job consists his integrity, and he don't think he has sinned against God.
How?
Thanks Jesus Christ saved me, I am not so righteous as Job, but I can stand before God and pray to the Lord for the salvation from Jesus blood.
