Matthew 26:34
26:34 Jesus said to him, “I tell you the truth, on this night, before the rooster crows, you will deny me three times.”
Matthew 26:74-75
26:74 At that he began to curse, and he swore with an oath, “I do not know the man!” At that moment a rooster crowed.
26:75 Then Peter remembered what Jesus had said: “Before the rooster crows, you will deny me three times.” And he went outside and wept bitterly.
