Luke 22:60

ἄνθρωπε, etc., man, I don't know what you are saying under shelter of the epithet Γαλιλαῖος, pretending ignorance of what the man said an evasion rather than a denial, with no cursing and protesting accompanying. A monstrous minimising of the offence, if Lk. had Mk.'s account before him, thinks J. Weiss; therefore he infers he had not, but drew from a Jewish-Christian source with a milder account. What if he had both before him, and preferred the milder? ἐφώνησεν ἀλεκ., immediately after the cock crew; but in Lk.'s account the reaction is not brought about thereby. In the parallels, in which Peter appears worked up to a paroxysm, a reaction might be looked for at any moment on the slightest occasion, the crowing of the cock recalling Christ's words abundantly sufficient. But in Lk. there is no paroxysm, therefore more is needed to bring about reaction, and more accordingly is mentioned.
