Mark 14:66-69

And when she saw Peter warming himself, she looked at him and said, “You also were with Jesus of Nazareth.” But he denied it, saying, “I neither know nor understand what you are saying.” And he went out on the porch, and a rooster crowed. And the servant girl saw him again, and began to say to those who stood by, “This is one of them.”
