Matthew 26:72

Now Peter was sitting outside in the court, and a maid came to him, saying, “You were also with Jesus, the Galilean!”

But he denied it before them all, saying, “I don’t know what you are talking about.”

When he had gone out onto the porch, someone else saw him and said to those who were there, “This man also was with Jesus of Nazareth.”

After a little while those who stood by came and said to Peter, “Surely you are also one of them, for your speech makes you known.”

Then he began to curse and to swear, “I don’t know the man!”

Immediately the rooster crowed.

Peter remembered the word which Jesus had said to him, “Before the rooster crows, you will deny me three times.” Then he went out and wept bitterly.
