Matthew 26:33-37

Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended.

Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.

Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.

Then cometh Jesus with them unto a place called Gethsemane, and saith unto the disciples, Sit ye here, while I go and pray yonder.

And he took with him Peter and the two sons of Zebedee, and began to be sorrowful and very heavy.
