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 after that I am risen, I will go before you into Galilee.’
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.’
But he spake the more vehemently, ‘If I should die with Thee, I will not deny Thee in any wise. Likewise also said they all.  Mark 14:26-31  (KJB)
