Peter denies the Lord three times
Peter said to him, "Even though they all fall away, I will not." And Jesus said to him, "Truly, I tell you, this very night, before the rooster crows twice, you will deny me three times." Mark 14:29-30 ESV
Having arrested Him, they led Him and brought Him into the high priest's house. But Peter followed at a distance. Now when they had kindled a fire in the midst of the courtyard and sat down together, Peter sat among them. And a certain servant girl, seeing him as he sat by the fire, looked intently at him and said, "This man was also with Him." But he denied Him, saying, "Woman, I do not know Him." And after a little while another saw him and said, "You also are of them." But Peter said, "Man, I am not!" Then after about an hour had passed, another confidently affirmed, saying, "Surely this fellow also was with Him, for he is a Galilean." But Peter said, "Man, I do not know what you are saying!" Immediately, while he was still speaking, the rooster crowed. And the Lord turned and looked at Peter. Then Peter remembered the word of the Lord, how He had said to him, "Before the rooster crows, you will deny Me three times." So Peter went out and wept bitterly.
