Mark 14:72

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 denied, saying, I know not, neither understand I what thou sayest. And he went out into the porch; and the cock crew.

But they that escape of them shall escape, and shall be on the mountains like doves of the valleys, all of them mourning, every one for his iniquity.

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

And Peter said, Man, I know not what thou sayest. And immediately, while he yet spake, the cock crew.

And David’s heart smote him after that he had numbered the people. And David said unto the LORD, I have sinned greatly in that I have done: and now, I beseech thee, O LORD, take away the iniquity of thy servant; for I have done very foolishly.

For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.

And Peter went out, and wept bitterly.

Then shall ye remember your own evil ways, and your doings that were not good, and shall lothe yourselves in your own sight for your iniquities and for your abominations.

That thou mayest remember, and be confounded, and never open thy mouth any more because of thy shame, when I am pacified toward thee for all that thou hast done, saith the Lord GOD.
