Mt 26:31-35
Then Jesus said to them, "This night all of you will have your faith in me shaken, for it is written: 'I will strike the shepherd, and the sheep of the flock will be dispersed'; but after I have been raised up, I shall go before you to Galilee." Peter said to him in reply, "Though all may have their faith in you shaken, mine will never be." Jesus said to him, "Amen, I say to you, this very night before the cock crows, you will deny me three times." Peter said to him, "Even though I should have to die with you, I will not deny you." And all the disciples spoke likewise.
