Ever since the beginning of the Babilonish Captivity, the diaspora has been Jewry's citadel and the Artaxerxes in question is Artaxerxes I (imperabat 465-424 B.C.) or Artaxerxes II (imperabat 404-359 B.C.) So we do not know whether the date of Ezra's mission was 458 B.C. or 397 B.C., or whether the date of Nehemia's mission was 445 B.C. or 384 B.C. (see G.F.
