Mark 14:30

And Jesus saith unto him, verily I say unto thee
As confident as thou art of standing by me, and abiding with me; that this day,
which was then begun; for the Jews reckoned their days from evening, as in ( Genesis 1:5 ) ; even in this night;
this night to be observed, this night of the passover, before it is past: before the cock crow twice;
for there was a first and second cock crowing, the one at midnight, and the other near break of day, and which last is properly the cock crowing: the word "twice" is left out in the Ethiopic version: thou shalt deny me thrice; as he did; (See Gill on Matthew 26:34).
