Matthew 26:69-75
73After a little while, those standing there went up to Peter
and said, "Surely you are one of them, for your accent
gives you away.“
74Then he began to call down curses on himself and he
swore to them, "I don't know the man!"
75Immediately a rooster crowed. Then Peter remembered
the word Jesus had spoken: "Before the rooster crows,
you will disown me three times." And he went outside
and wept bitterly.
