Mark 14:69-72 Amplified Bible (AMP)

69. And the maidservant saw him, and began again to say to the bystanders, This [man] is [one] of them.

70. But again he denied it falsely and disowned Him. And after a short while, again the bystanders said to Peter, Really, you are one of them, for you are a Galilean and your dialect shows it.

71. Then he commenced invoking a curse on himself [should he not be telling the truth] and swearing, I do not know the Man about Whom you are talking!

72. And at once for the second time a cock crowed. And Peter remembered how Jesus said to him, Before a cock crows twice, you will utterly deny Me [disclaiming all connection with Me] three times. And having put his thought upon it [and remembering], he broke down and wept aloud and lamented.
