And Peter being below in the courtyard, one of the slave girls of the chief priest came and having seen Peter warming himself, looked straight at him and said: ‘You too were with the Nazarene, Jesus.’ 

He denied him saying: ‘I do not know or understand what you are saying.’

And he went out to the gateway. And a  cock crowed. 

And the slave girl saw him and again began to say to the bystanders that ‘This man is one of them.’ But again he continued to deny him. 

And again bystanders at a distance said to Peter ‘ Truly  you are one of them, for you a Galilean.’

He began to curse (Jesus?) and swear an oath: ‘ I do not know this man, who you speak about.’

And immediately the cock crowed a second time. Peter remembered the words which Jesus had said to him : ‘Before the cock crowed twice, three times you will deny me.’

And he broke down and cried. 

O thou, who art the light of the minds that know thee,
the life of the souls that love thee,
and the strength of the wills that serve thee;
help us so to know thee that we may truly love thee;
so to love thee that we may fully serve thee,
whom to serve is perfect freedom.
Amen
