Mark 14:28

And when they had sung an hymn, they went out into the mount of Olives.

And Jesus saith unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep shall be scattered.

But Peter said unto him, Although all shall be offended, yet will not I.

And Jesus saith unto him, Verily I say unto thee, That this day, even in this night, before the cock crow twice, thou shalt deny me thrice.
