Matthew 26:72-74

73After a little time, other people who were standing at the gate spoke to Peter. They said, ‘We are sure that you too are one of that man's friends. We know this because you speak like people who live in Galilee.’

74Peter said to them very strongly, ‘I tell you that I do not know that man. God will surely punish me if this is not true!’ Immediately after Peter said this, the cockerel sang.
