Mike B has the right idea, although the four Deborahs or Yaels (Devorot? Yaelot?) from the Caesar set would also be inappopriate. And most of the weapons for the ring-hand guys in the Caesar set are probably also inappropriate for the 1st Century CE -- the axes and swords are more appropriate for the period of the Judges, David and Solomon some 800 years earlier, though the clubs and sticks could probably work for any time period. Still impressive how costume and dress among ordinary people probably changed very little over a milennium in the region.

Yeah, Sam, forgot about the kopesh...
Regarding costume, I believe some authorities claim that there is no evidence for the keffiya-style headdress before the Middle Ages, but table-top Hebrews (and school nativity plays) wouldn't be the same without it.
