Mark 14:27-31 NIV
“You will all fall away,” Jesus told them, “for it is written:
“ ‘I will strike the shepherd,
and the sheep will be scattered.’
But after I have risen, I will go ahead of you into Galilee.”
Peter declared, “Even if all fall away, I will not.”
“Truly I tell you,” Jesus answered, “today—yes, tonight—before the rooster crows twice you yourself will disown me three times.”
But Peter insisted emphatically, “Even if I have to die with you, I will never disown you.” And all the others said the same.
