Mark 14:29-31 King James Version (KJV)
29 But Peter said unto him, Although all shall be offended, yet will not I.
30 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.
31 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.
