Matthew 26:72-74

Revised Standard Version

⁷² And again he denied it with an oath, “I do not know the man.” 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.
