Jesus said unto him,
Verily I say unto you, That this night, before the cock crows, you shall deny me three times.

Theophylact of Ochrid
AD 1107
. With great audacity Peter alone promises not to stumble. Therefore Christ permitted him to fall in order to convince him not to be confident in himself but in God, and also to value Christ’s words as more trustworthy than his own knowledge of himself. Because Peter’s words "though all men shall stumble and fall" were full of arrogance, Christ shows him to be a braggart who did not know his own weakness. The Lord then foretells to him both the hour, that it will be "this night" and "before the cock crows," and also the number of the denials, that he will deny Him three times.
