Commentaries:
Robertson's Word Pictures (NT)
For when one saith (otan gar legh tiv). Indefinite temporal clause with the present subjunctive of repetition (Robertson, Grammar, p. 972). Each instance is a case in point and proof abundant of the strife.
Of Paul (Paulou). Predicate genitive, belong to Paul, on Paul's side.
Of Apollos (Apollw). Same genitive, but the form is the so-called Attic second declension. See the nominative Apollwv in verse I Corinthians 3:5.
Men (anqrwpoi). Just mere human creatures (anqrwpoi, generic term for mankind), in the flesh (sarkinoi), acting like the flesh (sarkikoi), not pneumatikoi, as if still yuxikoi. It was a home-thrust. Paul would not even defend his own partisans.
