Matthew 26:31-35

31 Then said Jesus to them, All of you will be turned away from me this night: for it is said in the Writings, I will put to death the keeper of the sheep, and the sheep of the flock will be put to flight.

32 But after I am come back from the dead, I will go before you into Galilee.

33 But Peter made answer and said to him, Though all may be turned away from you, I will never be turned away.

34 Jesus said to him, Truly I say to you that this night, before the hour of the cock's cry, you will say three times that you have no knowledge of me.

35 Peter says to him, Even if I am put to death with you, I will not be false to you. So said all the disciples.
