Matthew 26:73-75

Revised Standard Version Catholic Edition

⁷³ After a little while the bystanders came up and said to Peter, “Certainly you are also one of them, for your accent betrays you.” ⁷⁴ Then he began to invoke a curse on himself and to swear, “I do not know the man.” And immediately the cock crowed. ⁷⁵ And Peter remembered the saying of Jesus, “Before the cock crows, you will deny me three times.” And he went out and wept bitterly.
