1 sn The examples of marriage and divorce show that the ethical standards of the new era are still faithful to promises made in the presence of God. To contribute to the breakup of a marriage, which involved a vow before God, is to commit adultery. This works whether one gets a divorce or marries a person who is divorced, thus finalizing the breakup of the marriage. Jesus’ point concerns the need for fidelity and ethical integrity in the new era.
2 tn Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the narrative.
3 sn In Mark 14:69, the same slave girl made the charge. So apparently Peter was being identified by a variety of people.
4 tn Here and in v. 60 “Man” is used as a neutral form of address to a stranger.
