Mark 14:27-31

And Jesus said to them, “You will all fall away, because it is written, ‘I will strike the shepherd and the sheep will be scattered.’ But after I am raised, I will go ahead of you into Galilee.” But Peter said to him, “Even if they all fall away, certainly I will not!” And Jesus said to him, “Truly I say to you that today—this night—before the rooster crows twice, you will deny me three times!” But he kept saying emphatically, “If it is necessary for me to die with you, I will never deny you!” And they all were saying the same thing also.
