Mark 14:71

ἀναθεματίζειν. Lk. and Jn omit the cursing and swearing. The cursing would mean that he declared himself to be anathema, if what he said was not true; cf. Acts 23:12; Galatians 1:8-9; 1 Corinthians 16:22. Both the manner and the substance of his denial have increased. First he denied once that he was a follower of Jesus. Then he denied this several times. Now in very strong language he denies that he knows “this man of whom ye speak”; he cannot even now name the Master.
