Peter said three times that he did not know Jesus.

Luke 22:54-62

54 They seized Jesus and led him away. They brought him to the high priest’s house. Peter followed them at a distance. 55 They kindled a fire in the middle of the courtyard and sat down together. Peter sat among them. 56 As the light from the fire shone on his face, a female servant saw him and looked intently at him. She said, “This man was also with the man whom they have arrested!” 57 But Peter denied it, saying, “Woman, I do not know him!” 58 A little later someone else saw Peter and said, “You (sg) also are one of those who were with the man they arrested!” But Peter said, “Man, I am not one of them!” 59 About an hour later someone else said emphatically about Peter, “The way that this man speaks shows that he is from Galilee district. Certainly this man was also with the man whom they arrested, who is from Galilee!” 60 But Peter said, “Man, I do not know what you (sg) are talking about!” Immediately, while he was still speaking, a rooster crowed. 61 The Lord Jesus turned around and looked right at Peter. Then Peter remembered what the Lord had said to him, “This night, before the rooster crows, you (sg) will deny three times that you know me.” 62 And Peter went out of the courtyard and cried very sorrowfully.
