Matthew 26:70-75
26:70 But he denied it in front of them all: “I don’t know what you’re talking about!”
26:71 When he went out to the gateway, another slave girl saw him and said to the people there, “This man was with Jesus the Nazarene.”
26:72 He denied it again with an oath, “I do not know the man!”
26:73 After a little while, those standing there came up to Peter and said, “You really are one of them too – even your accent gives you away!”
26:74 At that he began to curse, and he swore with an oath, “I do not know the man!” At that moment a rooster crowed.
26:75 Then Peter remembered what Jesus had said: “Before the rooster crows, you will deny me three times.” And he went outside and wept bitterly.
