Peter’s Denial Foretold
31 Then Jesus said to them, “You will all become deserters because of me this night; for it is written,
‘I will strike the shepherd,
32 But after I am raised up, I will go ahead of you to Galilee.” 33 Peter said to him, “Though all become deserters because of you, I will never desert you.” 34 Jesus said to him, “Truly I tell you, this very night, before the cock crows, you will deny me three times.” 35 Peter said to him, “Even though I must die with you, I will not deny you.” And so said all the disciples.
