John 13:36-38 - Peter's Denials Predicted
36 "Master," inquired Simon Peter, "where are you going?" "Where I am going," replied Jesus, "you cannot be my follower now, but you shall be later."
37 "Master," asked Peter again, "why cannot I follow you now? I will lay down my life on your behalf.
38 "You say you will lay down your life on my behalf!" said Jesus; "in most solemn truth I tell you that the cock will not crow before you have three times disowned me."
