Mark 14:70-72

14:70 But he denied it again. A short time later the bystanders again said to Peter, “You must be one of them, because you are also a Galilean.” 14:71 Then he began to curse, and he swore with an oath, “I do not know this man you are talking about!” 14:72 Immediately a rooster crowed a second time. Then Peter remembered what Jesus had said to him: “Before a rooster crows twice, you will deny me three times.” And he broke down and wept.
