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

Matthew 26:31-35

31 On the way, Jesus told us, “This night all of you will desert me because of what will happen to me! This is certain to happen because these words that God said are written in the Scriptures: ‘I will cause the shepherd to be killed, and all the sheep will be scattered {scatter}.’ 32 But after I have died and become alive again, I will go ahead of you to Galilee district and meet you there.” 33 Peter replied, “Perhaps all the other disciples will desert you when they see what happens to you, but I certainly will never leave you!” 34 Jesus replied to him, “The truth is that this very night, before the rooster crows, you will say three times that you do not know me!” 35 Peter said to him, “Even if they kill me while I am defending you, I will never say that I do not know you!” All the rest of us disciples also said the same thing.
