Mark 14:27-31
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.
