Mark 14:28 KJV

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.
