Matthew 26:33-36 King James Version (KJV)
33 Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended.
34 Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.
35 Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.
36 Then cometh Jesus with them unto a place called Gethsemane, and saith unto the disciples, Sit ye here, while I go and pray yonder.
