Mark 14:27-31 NIV

[27] “You will all fall away,” Jesus told them, “for it is written: “ ‘I will strike the shepherd, and the sheep will be scattered.’ [28] But after I have risen, I will go ahead of you into Galilee.” [29] Peter declared, “Even if all fall away, I will not.” [30] “Truly I tell you,” Jesus answered, “today—yes, tonight—before the rooster crows twice you yourself will disown me three times.” [31] But Peter insisted emphatically, “Even if I have to die with you, I will never disown you.” And all the others said the same.
