      Zenas--the contracted form of Zenodorus.
      lawyer--a Jewish "scribe," who, when converted, still retained the title from his former occupation. A civil lawyer.
      Apollos--with Zenas, probably the bearers of this Epistle. In 1Co 16:12, Apollos is mentioned as purposing to visit Corinth; his now being at Corinth (on the theory of Paul being at Corinth when he wrote) accords with this purpose. Crete would be on his way either to Palestine or his native place, Alexandria. Paul and Apollos thus appear in beautiful harmony in that very city where their names had been formerly the watchword of unchristian party work. It was to avoid this party rivalry that Apollos formerly was unwilling to visit Corinth though Paul desired him. HIPPOLYTUS mentions Zenas as one of the Seventy, and afterwards bishop of Diospolis.
