The words πολλοὶ γάρ εἰσιν κλητοί, ὀλίγοι δὲ ἐκλεκτοί (for many are called but few chosen) have probably been added at the end of this verse by copyists who remembered another parable which has these words at the end (see 22:14). It is possible, but less likely, that these additional words are original and were accidentally omitted by a copyist whose eye jumped from the end of the word ἔσχατοι to the end of the word ἐκλεκτοί.
