Luke 22:31-34 (KJV)

31 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:

32 But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.

33 And he said unto him, Lord, I am ready to go with thee, both into prison, and to death.

34 And he said, I tell thee, Peter, the cock shall not crow this day, before that thou shalt thrice deny that thou knowest me.
