That I am not a whit behind the very chiefest apostles (mhden usterhkenai twn uperlian apostolwn). Perfect active infinitive of usterew, old verb to fall short with the ablative case. The rare compound adverb uperlian (possibly in use in the vernacular) is probably ironical also, "the super apostles" as these Judaizers set themselves up to be. "The extra-super apostles" (Farrar). Also in Galatians 12:11 . He is not referring to the pillar-apostles of Galatians 2:9 .
