Zenas, "a person 'skilled in the Law par excellence, the Torah, even the whole OT'"

     Reidar Hvalvik, "Named Jewish believers connected with the Pauline mission," in Jewish believers in Jesus:  the early centuries, ed. Oskar Skarsaune and Reidar Hvalvik (Peabody, MA:  Hendrickson Publishers, Inc., 2007), 176-177 (154-178).  Most strikingly, "Admittedly Zenas is a contraction of Zenodorus, 'gift of Zeus,' and it is argued that it is 'unlikely' that a Jewish lawyer would have such a pagan name [('So I. Howard Marshall')].  This argument is, however, not valid.  There are several examples of Jews with typical pagan names, e.g., the female equivalent Zenodora ['Used of a Jewish woman in Rome (CIJ 43; cf. Noy, Jewish inscriptions, 100)'], further Dionysius, Apollonius, and Serapion."
     "The second name to be examined more closely is Lois, the grandmother of Timothy (2 Tim 1:5). . . .  Her name, Lois, is probably Cilician, but this does not help us very much in light of what we know of Jewish names.  There is, however, a 50 percent chance that Lois was a Jew.  The fact that she is juxtaposed with Timothy's Jewish mother increases the probability" (177).
