Jesus predicted that Peter would deny three times that he knew Jesus.

Mark 14:27-31

27 While they were on their way, Jesus said to them, “It has been {The prophets have} written in the Scriptures that God said about me, ‘I will kill the shepherd and his sheep will scatter.’ Those words will come true. When they are about to capture me, all of you will leave me and run away. 28 But after I have been made {God has made me} alive again, I will go ahead of you to Galilee district and meet you there.” 29 Then Peter said to him, “Perhaps all the other disciples will leave you, but not I! I will not leave you!” 30 Then Jesus said to him, “The truth is that this very night, before the rooster crows a second time, you yourself will deny three times that you know me!” 31 But Peter replied strongly, “Even if they kill me as I defend you, I will never deny that I know you!” And all the other disciples said the same thing.
